bicarbonate

These salts can be prepared by the reaction of carbon dioxide with metal oxides and metal hydroxides, respectively.CO₂ + O₂ → CO₃²⁻
CO₂ + OH⁻ → HCO₃⁻ For example, when an aqueous solution of sodium hydroxide (NaOH) is saturated with carbon…

Bicarbonate participates in the transport of carbon dioxide and in the regulation of pH. Phosphate also has a buffering effect on the pH of the blood and is vital for chemical reactions of cells and for the metabolism of calcium. Iodide is transported through plasma…

…is a mild stimulant of bicarbonate secretion from the pancreas, and is a powerful stimulant of the secretion of water and electrolytes by the small and large intestines. It relaxes the sphincters and slows intestinal transit time. There is another group of peptide messengers that is found in quantity within…

…extracellular fluid is chloride, while bicarbonate is the second most important. In contrast, the major cation of the intracellular fluid is potassium, and the major anions are proteins and organic phosphates. The marked differences in sodium and potassium concentrations between the intracellular and extracellular fluid of cells are not fortuitous…

, filtered bicarbonate). Current evidence indicates that both filtration and secretion are essential to hydrogen ion excretion and that both proximal and distal convoluted tubules are involved.
