3) Alcohol intoxication (e.g. acides Définition d'alcalin : relatif à des composés d’aluminium et de sels alcalins ayant des propriétés basiques qualifie une roche constituée d’au moins autant de produits alcalins que de calcium relatif aux alcalis. From this article acid vs base. Elevated loss of bicarbonates has normal AG. Buffers however are not capable of eliminating those acids and bases from body. Correction is solving the acid-base problem in the spot where it started. Normal values are 0 ± 2,5 mmol/l. It is shown below that these processes are connected (e.g. This increased cation concentration must be accompanied by replenishing of anions because electroneutrality must be maintained (i.e. 15 000 – 20 000 mmol CO2 (therefore same amount of carbonic acid) is produced every day. This loss of anions is compensated by replenishing of other anions, predominantly bicarbonates (and increased bicarbonates mean alkalosis), 2) Increased cation concentration (most commonly Na+), 3) Increased alkali intake (e.g. Ratio of conjugated base and acid could be calculated from relation between pH and pK. Bicarbonate buffer is the most important buffer system in blood plasma (generally in the extracellular fluid). Therefore it is not surprising that venous pH and pH of interstitial fluid is lower (i.e. One of the important buffers in blood is albumin. Immergez un os de poulet dans un jus de citron. Elapsed time: 138 ms. Word index: 1-300, 301-600, 601-900, More, Expression index: 1-400, 401-800, 801-1200, More, Phrase index: 1-400, 401-800, 801-1200, More. The most important acid is CO2. stop breathing). Therefore it is really important to know the ratio. Rétablir le pH dans un corps trop acide : Doctissimo vous dresse la liste des facteurs qui "acidifient" votre corps et ceux qui au contraire "l’alcalinisent". Si pH > 7 : la solution … Anion of this acid eliminates bicarbonate. Je me demandais si mon ph urinaire était trop acide et cela me provoquait des piques,des brulures. Every acid in the body apart from carbonic acid is so called metabolic acid. Identifiant BDSP 9562 Création de la notice 1994-06 Dernière mise à jour 1994-06. metabolic component must be always assessed with knowledge of pCO2 in particular patient). Respiratory disturbances are indicated by shifts in pCO2 (respiratory disorder – hyper- or hypocapnia). excretion of H+ in proximal tubule is connected with reabsorption of HCO3– in the same place or excretion of H+ in distal tubule is connected with production of HCO3– in the same place). Kidneys perform (1) increased excretion of H+ and (2) new bicarbonate production (intercalated cells type A). For example change of protein structure (i.e. Metabolic acids are non-volatile, therefore they have to be neutralized and either metabolised, or eliminated by kidneys. spine deformities). Our wines celebrate the spirit of taking on any challenge in life, no matter how insurmountable it may seem. Il peut être utile de vérifier le pH de votre urine à l'aide d'un papier pHydrion de pH Santé Beauté afin de déterminer si vos choix alimentaires vous assurent l'équilibre voulu. Positive value indicates excess of bases (base excess), hence metabolic alkalosis. mannitol de… Au contraire mon frere!...I'm out digging F***ing potatoes to get Butyric acid bacteria. sodium chloride, essential amino acids (including L-phenylalanine), non-essential amino acids, L-arginine hydrochloride, sucrose, D … This thousand fold gradient is however maximal, thus the lowest achievable pH of the urine is 4,4 (40 μmol/l H+) – compare this value with value of the pH in blood: 7,4 (40 nmol/l H+). We use status of bicarbonate buffer for clinical evaluation of patient´s acid-base balance. Par exemple, "petit" est le contraire de "grand", "généreux" l'opposé de "radin". It is defined as either (1) combination of two or more basic disturbances of acid-base balance, or (2) combination of more causes that cause the same acid-base balance disturbance, (3) or both. Even in alkalosis nephrons however excrete less bicarbonate than they retain. Unmeasurable is not accurate term, more precise is commonly non-measured. They are continually produced by metabolism (incomplete oxidation of TAG, carbohydrates, proteins). Excessive production of acids leads to high AG. Rechercher le contraire d'un autre mot ... qui n'est ni acide, ni basique, pour un élément chimique impartial qui ne prend pas parti peu marqué, sans passion, sans originalité, sans éclat. 1) Accumulation of “metabolic” acid. In Chemistry, pH measures the relative basicity and acidity of an aqueous (solvent in water) solution. Three types of reactions can be distinguished from point of view of the acid-base balance. Dans l'acidose métabolique extracellulaire (pH, 6,90), au contraire, le pH cellulaire est abaisse dans Ic diaphragme déplété, Ia décarb-oxylation du citrate augmentée et le … Au contraire, ces acides peuvent être utilisés comme sub-strat lorsque le pH du milieu extérieur est ~ pH du milieu intérieur. Role of erythrocytes and haemoglobin in the acid-base balance. Yes, it's extremely toxic. Acidosis is process that leads to the drop in pH value. The list below is made according to order when they act: Buffers react immediately – acute regulation. H2CO3 is produced from CO2 hence it is possible to express carbonic acid concentration as partial pressure of CO2 (pCO2) because pCO2 is directly proportional to CO2 concentration. Please report examples to be edited or not to be displayed. In carbonic acid dissociation H+ is produced. This is compensated by decrease of bicarbonate. Cosmetics and … This is often called Kussmaul acidotic breathing (breathing centre is stimulated by high H+ concentration). 2. (fr) L'acido nitroso è un acido debole di formula HNO2. ... Un antonyme est un mot dont le sens est opposé à celui d'un autre mot. In this condition ratio between ionised and bound calcium is changed. lower than 6,8 are incompatible with life. 1) Increase in concentration of ions that physiologically make the AG. α = 0,226 for pCO2 in kPA, α = 0,03 for pCO2 in mmHg). Hyperventilation causes increased elimination of carbon dioxide and that leads to hypocapnia (decreased pCO2). To the lumen of the proximal tubule is transported H+. Lors d'une acidocétose, le pH sanguin est acide et l'haleine des patients présente une odeur d'acétone et entraîne des douleurs abdominales. The kidneys take part in maintaining the acid-base balance by means of: 1) Reabsorbing, excreting and producing bicarbonate. Bicarbonate are lost most commonly from the GIT. It can be stated that metabolic acidosis is pH that is too acidic compared with given pCO2 (i.e. Base is au contraire molecule that can cleave off OH– (Arrhenius) or acceptor of H+ (Brönsted). Le pH (qui signifie potentiel hydrogène) est une grandeur sans unité qui mesure l’acidité ou la basicité d’une solution. Acids can be divided into two groups: (1) volatile acids (respiratory acids), (2) non-volatile acids (metabolic acids). Respiratory disturbances are compensated by the kidneys. Acid reflux is the result of too little base! [Na+] = 140 mmol/l or [HCO3–] = 25 mmol/l, are three orders of magnitude higher). These cells absorb CO2 from the blood and inside the cells carbon dioxide reacts with water and carbonic acid is thus produced, catalysed by the enzyme carboanhydrase. metabolic disturbances are solved by metabolic component of acid-base balance. Maintenance of the internal environment is one of the vital functions (it has same importance as circulation or respiration). breathing in lack of oxygen). Third step is correction by kidneys. paterne. Je me demandais si mon ph urinaire était trop acide et cela me provoquait des piques,des brulures. This is because pCO2 is lowered and thus – to keep equilibrium – part of bicarbonate is converted to CO2. Inorganic non-volatile acids are predominantly excreted in urine. In the kidney is H+ excreted as NH4+. CMPNANCY - Centre de Médecine Préventive. In the body correction takes place only in metabolic disorders, i.e. Inorganic non-volatile acids are: (1) H2SO4 (sulphuric acid is produced by oxidation of sulfhydryl groups – e.g. This is important because excretion of NH4+ is significantly regulated when the acid-base balance is disturbed. Respiratory tract can eliminate (or cumulate) volatile carbonic acid by means of eliminating CO2 (or cumulate it). lorsque le pH du milieu extracellulaireest inférieur au pH du milieu intracellulaire par suite d'une ac-cumulation de "acide dans le mycélium. That leads to the hyperkalemia. acide adj. This pH could be calculated by means of the Henderson-Hasselbalch equation: Henderson-Hasselbalch equation for bicarbonate buffer (HCO3–/CO2): α is conversion factor, that is used for calculation of molar concentration (mmol/l) from partial pressure of CO2 (pCO2). When respiratory system is not capable of normal CO2 elimination (carbon dioxide could be eliminated too much or too few) respiratory acid-base balance disturbances come into existence. 7,2) is acidosis! In Henderson-Hasselbalch equation above you should notice that for pH that buffers keep depends primarily on ratio of conjugated base and acid (Of course concentration of each component is important but not that much). Déséquilibre acide-alcalin (suite 2) Un pH trop acide ou trop alcalin est contraire à un bonne oxygénation des cellules. AMP, ADP, and ATP). This buffer consists of weak acid H2CO3 (pK1 = 6,1) and conjugated base HCO3– (bicarbonate). Cette solution est bleue. Increased pCO2 causes decreased pH. En milieu basique, au contraire, la sorption est diminuée en raison de la com-plexation des ions cobalt par l’acide humique soluble. From a very early age, Svante Arrhenius showed signs of a brilliant intellect. High aldosterone causes increased retention of Na+. In all these conditions at first buffering of excessive H+ takes place (it is carried out by bicarbonate and non-bicarbonate bases). Lactate acidosis is typical companion of RAC, shock or overdose of biguanides (metformin). Alkalosis leads to efflux of H+ from the cells. Bicarbonate reabsorption takes place in proximal tubule cells. Kalemia is influenced most by acid-base balance disturbances. Overdose of salicylates (Aspirin) can cause MAC as well. Briefly, 1 ml of urine was centrifuged at 13,500 rpm for 10 min and the resulting pellet was resuspended in 200 μl of filter-sterilized buffer consisting of 20 mM Tris-Cl (pH 8), 2 mM EDTA, 1.2% Triton X-100, and 20 μg/ml lysozyme and supplemented with 30 μl of filter-sterilized mutanolysin (5,000 U/ml; Sigma-Aldrich; St. Louis, MO). H+ is transported by Na+/H+ antiport  H+ reacts with HCO3– and H2CO3 is thus produced. Acid-base balance status is assessed according to the status of the bicarbonate buffer. L'acide nitreux est un composé chimique de formule HNO2. Which one of these fates of ammonium is favoured closely depends on status of the acid-base balance: a) NH4+ → urea + 2 H+ → acidification of the body, H+ + HCO3– → H2O + CO2 (consumption of bicarbonate–), b) NH4+ → glutamine synthesis → H+ is not produced, glutamine is taken up by the kidneys. 1 La chimie est pHun! A 25 °C, une solution est acide si son pH est inférieur à 7, neutre si son pH vaut 7, basiquesi son pH est supérieur à 7. Hypoproteinemia is caused by liver failure, nephrotic syndrome or malnutrition. 3) Hyperaldosteronism. Pour un acide faible : pH = 1/2 pKa – 1/2log C. 4) Renal insufficiency leads to condition when normally excreted acids are cumulated (sulphates, phosphates, some other anions). Le contraire d'alcalin. In lungs HCO3– is changed to CO2, using enzyme CA. Si pH 7 : la solution est acide. pH = 7,4 (H+concentration is 40 nmol/l). - Duration: 6:01. Les antonymes du mot acide présentés sur ce site sont édités par l’équipe éditoriale de antonyme.org Exact: 310. CMPNANCY - Centre de Médecine Préventive. Il suffit pour cela de mesurer la quantité de capsaïcine contenue dans chaque variété de piment et d'en déterminer sa force. pCO2 is regulated by respiratory tract (by means of ventilation – respiratory rate and depth of breathing). Acid is defined as molecule that can cleave off H+ (Arrhenius) or donor of H+ (Brönsted). Les indices qui montrent que votre organisme est trop acide et comment y remédier rapidement ! Values mentioned above apply for arterial blood. neuromuscular disorders, CNS disorders, intoxications (opiates), asthmatic paroxysm), 4) Thorax movement restriction (e.g. Alkalosis is au contraire process that leads to theincrease inpH value. Identifiant BDSP 9562 Création de la notice 1994-06 Dernière mise à jour 1994-06. Human organism (healthy or not) every day produces great quantities of acids – source of protons. This leads to excessive use of fatty acids as the main energy source. Si pH 7 : la solution est acide. Next important concept is that higher bicarbonate concentration increases pH, lower bicarbonate concentration decreases pH. L'antonyme est un mot dont le sens est le contraire d'un autre mot. esters of organic substances, e.g. © 2013-2020 Reverso Technologies Inc. All rights reserved. Laboratory assessment of the acid-base balance status consists of: (1) acid-base balance parameters (pH, [HCO3–], pCO2, pO2 a BE) and (2) examination of other substances that can alter acid-base balance. (it) Overview Information Eicosapentaenoic acid (EPA) is an omega-3 fatty acid. Overview Information Eicosapentaenoic acid (EPA) is an omega-3 fatty acid. Intensive change of blood gases occurs in working tissue. CO2 diffuses to erythrocytes. It provides 35 % of buffering capacity of blood, remaining proteins provide only 7 %. This should mean that bicarbonate buffer would work best in range 5,1-7,1, but in pH 7,4 it is very effective because it is open That is: organism is able to actively change both components. Main buffer systems according to body compartments. These alcohols are metabolised to strong organic acids (formic acid, oxalic acid). 3) Salicylates poisoning (Aspirin) – fever, etc…. Trouver le contraire d'un mot. It is so called examination of the ABR parameters by Astrup (ASTRUP). pH = 7,4 (H+ concentration is 40 nmol/l). suave. These systems maintain pH value 7,36-7,44. Chemical buffers are capable of stopping increase in acids or bases. Les cellules étouffent littéralement lorsque le déséquilibre acide-alcalin est trop marqué, l'organisme déclenche une respiration automatique pour rétablir l'équilibre. Le vinaigre de cidre est particulièrement intéressant en raison de sa richesse en acide acétique (entre 5 et 8 %), qui lui confère de nombreuses propriétés santé. Values differ in different body compartments hence there are different H+ concentrations. This is provided by larger excretion of HCO3– by the kidneys. Arterial blood must not contain air bubbles (because presence of air could alter pO2 (increase), pCO2 (decrease) and pH (increase)) and analysis should take place as soon as possible. Short-term and acute changes in acid-base balance can be balanced by buffers. This increase in difference could be revealed by AG. Little mistake in big numbers lead to greater mistake in the result. In glomerular ultrafiltrate there is filtered bicarbonate. Negative value indicates excess of acids (so the value is negative). Many chemical Respiratory system regulates carbon dioxide. Compensation is decreased HCO3–. mannitol de… I.e. Factors influencing the fate of herbicides in soil 2.1 Physicochemical interactions with soil Soil is one of the main regulators of herbicid e mobility in the environment. Respiratory alkalosis is caused by hyperventilation. In the intercalated cells type A (in the distal tubule and the collecting duct) the transport of proton to the lumen is based on active transport (H+-ATPase). Mechanism of volume expansion on citrate, ammonia, and acid excretion in the rat Potassium-depleted rats receiving sodium chloride or i.v. The kidneys retain or excrete HCO3– in order to (1) keep ratio HCO3– : pCO2 and (2) draw pH nearer to the normal values. أسود المعرفة 68,387 views 21:11 Well, what makes you think it should? Comm… This condition makes tissues to process glucose in anaerobic glycolysis. Skin surface pH : A protective acid mantle : An acidic skin-surface pH promotes barrier function and fights infection Author YOSIPOVITCH, G 1; MAIBACH, H. I 1 [1] Department of Dermatology, UCSF Medical Center, San Francisco, CA, United States Issue title Sun products formulary Source. Therefore when there is increased AG it indicates that commonly non-measured acids accumulated. pCO2 depends – besides other things – on the pulmonary ventilation (= respiratory minute volume). There are two important urine buffers: (1) ammonium buffer (NH3/NH4+) and (2) phosphate buffer. the acid-base disturbance is caused by the other system. 2) Hypoproteinemia – proteins are anions thus decreased protein concentration is compensated by increased bicarbonate concentration (i.e. H2CO3 is produced by reaction of carbon dioxide (CO2 is acid-forming oxide) with water. Regulatory mechanisms 2: Nervous regulation, Responsible for majority of the titratable urine acidity, Significant: elimination of ammonium nitrogen and protons; cation. dichlorophenoxyacetic acid, metsulfuron-me thyl), based on our own research data. K+ is excreted in the urine instead of H+. phosphoric acid, sulphuric acid, uric acid, …). AG calculation is useful in differential diagnosis of MAC. 2) Loss of bicarbonates (this loss of anion is accompanied by loss of cation, it is not surprising that most abundant cation (Na+) is lost mostly), 3) Loss of cations, predominantly Na+. Je ne sais pas ce que j'ai et j'aimerai bien que vous m'aidiez. Observez comment a évolué l’os de poulet. Results: 310. Nom commun. Metabolic acidosis is the most common acid-base balance disorder. Un couple acide-base est constitué d'un acide et d'une base dits conjugués, qui s'obtiennent l'un à partir de l'autre par échange (gain ou perte) d'un proton H +. Causes of RAC mentioned above can sometimes cause decreased pO2 too. Hypokalemia is mostly dangerous for the heart – membrane signal transmission. Compensation thus means metabolic disturbances are compensated by respiratory system and respiratory disturbances are compensated by metabolic components of acid-base balance. Many chemical One of the causes is the accumulation of the acids. There are particular situations when we need to measure commonly non-measured acids (anions) concentrations. dichlorophenoxyacetic acid, metsulfuron-me thyl), based on our own research data. The experimental results suggests that the pH value or the ionic strength would affect the extent of DOC removal, chlorine consumption, and by-products formation. They become part of AG.

For example bicarbonate buffer (pH = 7,4; pK = 6,1): The ratio in bicarbonate buffer is 20:1 (HCO3– : CO2). Examples are used only to help you translate the word or expression searched in various contexts. 1 mmol/kg of body weight is produced every day. The experimental results suggests that the pH value or the ionic strength would affect the extent of DOC removal, chlorine consumption, and by-products formation. Buffers are substances capable of releasing and binding H+. Il suffit pour cela de mesurer la quantité de capsaïcine contenue dans chaque variété de piment et d'en déterminer sa force. To maintain electrical charges the same, K+ enter the cells in order to replace H+. Rude or colloquial translations are usually marked in red or orange. Anion gap is a quantity which is almost equal to the sum of concentrations of “unmeasurable” anions (albumin – plasma proteins, phosphates, sulphates, organic anions). They secrete bicarbonate and gain H+. The respiratory system modulates pCO2 and the kidneys modulate concentration of bicarbonate. Factors influencing the fate of herbicides in soil 2.1 Physicochemical interactions with soil Soil is one of the main regulators of herbicid e mobility in the environment. paterne. Four basic acid-base balance disturbances are distinguished: 1) Respiratory acidosis (RAC): decreased blood pH; its primary cause is increased pCO2, 2) Respiratory alkalosis (RAL): increased blood pH; its primary cause is decreased pCO2, 3) Metabolic acidosis (MAC): decreased blood pH; its primary cause is decreased BE ([HCO3–]), 4) Metabolic alkalosis (MAL): increased blood pH; its primary cause is increased BE ([HCO3–]). Organism is acidified by these processes: Carbohydrates → glucose → pyruvate, lactate + H+, Triacylglycerol → fatty acids, ketone bodies + H+, Proteins → amino acids→ sulphate, urea + H+. Now we mention some particular states that lead to MAL: 1) Vomiting – loss of HCl (thus loss of H+). Therefore they have no influence on proton overall balance. Est-elle acide, neutre ou basique. There is however one very similar quantity – base deficit (BD). The problem is not the result of too much acid – au contraire! In Subchapter 7/6 is pointed out that maintenance of stable pH, also called isohydria, is one of the basic components of the internal environment: (1) isohydria, (2) isovolumia (stable volume), (3) isoosmolarity (stable tonicity), and (4) isoionia (stable ion composition). Translations in context of "pH acide" in French-English from Reverso Context: Filtration sur tourbe pour aider à maintenir un pH acide. 4) Iatrogenic bases delivery (e.g. more acidic) than arterial pH. Generated protons are buffered by haemoglobin. Average value in arterial blood is 5,3 kPa = 40 mmHg. The specimens are obtained from arterial blood (a. radialis or a. femoralis), sometimes it is necessary to collect capillary blood too. Extensive deviations of pH value can cause serious consequences. 760 mmHg ≈ 100 kPa). Par nature acide (pH compris entre 2 et 3), le vinaigre a pourtant un effet alcalinisant chez les personnes en bonne santé. This method is unfortunately dependent on accuracy of the measurements. Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula C 14 H 8 O 2. chimie : pH > 7 acide neutre. (pH measurement, [HCO3–] a pCO2). Na+ is transported to the blood among other things by active transport – i.e. 2) Excessive production of ketone bodies (acetoacetic acid and β-hydroxybutyric acid). You should recall that albumin binds approximately 50 % of plasma calcium. chimie : pH < 7 ... Un antonyme est un mot dont le sens est opposé à celui d'un autre mot. Subchapter Authors: Josef Fontana and Petra Lavríková, II. Conversion relationship between mmHg and kPa is: 1 Pa = 0,0075 mmHg (i.e. 2. In the European Union, it is also known under the E number E955. Bicarbonates are transported to the blood, whilst ammonium ions are excreted to the blood. qui affecte un comportement bienveillant et doucereux. Bicarbonate forms with H+ carbonic acid that forms CO2 and water, carbon dioxide is eliminated by the lungs. Chemical buffering systems deal with pH deviations in common metabolism. In order to eliminate as much H+ as possible it is necessary to buffer H+ in the urine. 1/ semblerait que ces acides tra- Background Au Contraire wines are crafted for those who aim to live life to the fullest, who revel in turning the every day ordinary into something extraordinary. As organic non-volatile acids are products of metabolism in normal conditions they are oxidized completely to CO2 and H2O. These substances are for example: 3) Metabolites: [urea], [creatinine], [ketone bodies]. (2) Bicarbonate however traverse basolateral membrane into interstitial fluid (and then to the blood of the peritubular capillaries). (1) proton-productive, (2) proton-consumptive, (3) proton-neutral. In conditions of rising pH (alkalosis) type B of the intercalated cells start to act. pH is used for express concentration of the protons: Plasma and extracellular space concentrations of the protons are held in very narrow physiologic range. There is 40 nmol/l of protons in the arterial blood physiologically (note that concentrations of other plasma ions, e.g. Unités du SI et CNTP, sauf indication contraire. ... qui n'est ni acide, ni basique, pour un élément chimique impartial qui ne prend pas parti peu marqué, sans passion, sans originalité, sans éclat. L’os est devenu mou. Un couple acide-base est constitué d'un acide et d'une base dits conjugués, qui s'obtiennent l'un à partir de l'autre par échange (gain ou perte) d'un proton H +. In the red blood cell CO2 either (1) binds to haemoglobin (and carbaminohemoglobin is formed), or (2) reacts with water. When there is accumulation of commonly non-measured acids unexpected rise in difference of measured cations and anions. It is stable under heat and over a broad range of pH … Yes, it can etch, or perhaps even dissolve away glass and ceramic. Every day is excreted 30-50 mmol of NH4+. modifier L' acide phénylpyruvique (ou acide phényl-pyruvique ) est un acide organique de formule semi-développée C 6 H 5 CH 2 CO-COOH, issu de la désamination oxydative de la phénylalanine (Phe ; F), un acide aminé . The most important volatile acid is carbonic acid (H2CO3). Both bicarbonate resorption, and new bicarbonate production (both mentioned above) need transport of H+ (protons) to the tubules (protons are derived from carbonic acid dissociation). Dans les trois suspensions et en présence d'EDDS, la photodégradation de E2 augmente significativement dans la zone de pH neutre et basique (de 5,0 à 9,0). In acidosis is glutaminase activated in the kidneys. En milieu basique, au contraire, la sorption est diminuée en raison de la com-plexation des ions cobalt par l’acide humique soluble. Kidneys react in hours-days. Following table shows buffering capacity of blood buffers. Voici une liste des antonymes pour ce mot. In this section are in detail described basic processes as reabsorption of bicarbonate, new bicarbonate production, ammonium ion production, proton excretion in kidneys, bicarbonate secretion. ascorbic acid, hydrolyzed casein, sodium chloride, sucrose, dried lactose, sodium bicarbonate, sodium carbonate Dengue (Dengvaxia) 6/2019 . Skin surface pH : A protective acid mantle : An acidic skin-surface pH promotes barrier function and fights infection Author YOSIPOVITCH, G 1; MAIBACH, H. I 1 [1] Department of Dermatology, UCSF Medical Center, San Francisco, CA, United States Issue title Sun products formulary Source. Chaque piment ne procure pas la même sensation de piquant, certains semblent doux, d'autres paraissent beaucoup plus forts. There are however some diseases of the GIT (diarrhoea, short intestine syndrome, etc…) when bicarbonates are resorbed insufficiently. This process is called Hamburger´s effect (chloride shift). Source of acids in the body is chiefly metabolism, source of bases is predominantly nutrient.
