The carbonic anhydrases (or carbonate dehydratases) form a family of enzymes that catalyze the rapid interconversion of carbon dioxide and water to bicarbonate and protons (or vice versa), a reversible reaction that occurs relatively slowly in the absence of a catalyst.
Bicarbonate (HCO3). This electrolyte is an important component of the equation that keeps the acid-base status of the body in balance. Water + Carbon Dioxide = Bicarbonate + Hydrogen. The lungs regulate the amount of carbon dioxide, and the kidneys regulate bicarbonate (HCO3).This electrolyte helps buffer the acids that build up in the body as normal byproducts of metabolism. For example, when muscles are working, they produce lactic acid as a byproduct of energy formation.icarbonate (HCO3).
