Carbonic anhydrase is one of a family of enzymes that catalyze the rapid conversion of carbonic acid to bicarbonate and protons, a reaction that occurs rather slowly in the absence of a catalyst. The primary function of the enzyme in animals is to interconvert carbon dioxide and bicarbonate to maintain acid-base balance in blood and other tissues, and to help transport carbon dioxide out of tissues.
