Bicarbonate buffer system - Wikipedia

La concentration en bicarbonate dans le sang est entre 22 et 26 mmol/L . Le caractère amphotère du bicarbonate (sa place intermédiaire dans l'équilibre), lui fait jouer un rôle de tampon. Cette fonction de tampon des bicarbonates existe notamment dans le sang, avec un rôle très important pour le maintien du pH (cf. Homéostasie). De nombreux organes interviennent dans la régulation du taux des bicarbonates, donc du pH : … WebTraductions en contexte de "concentration of carbonate" en anglais-français avec Reverso Context : As ocean acidity increases and the concentration of carbonate ions decrease, these species first find it more difficult to make their shells. Bicarbonate (HCO 3) is a vital component of the pH buffering system of the human body (maintaining acid–base homeostasis). 70%–75% of CO2 in the body is converted into carbonic acid (H2CO3), which is the conjugate acid of HCO 3 and can quickly turn into it. With carbonic acid as the central intermediate … Meer weergeven In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogencarbonate ) is an intermediate form in the deprotonation of carbonic acid.
