•History

Carbonic anhydrase, enzyme found in red blood cells, gastric mucosa, pancreatic cells, and renal tubules that catalyzes the interconversion of carbon dioxide (CO2) and carbonic acid (H2CO3). Carbonic anhydrase plays an important role in respiration by influencing CO2 transport in the blood. The enzyme also functions in the formation of hydrochloric acid by the stomach.
