Trace element present in carbonic anhydrase is?
Correct Answer: Zinc
Description: Zn is an essential component of several enzymes like carbonic anhydrase, alcohol dehydrogenase, alkaline phosphatase, carboxypeptidase and superoxaide dismutase. 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 rather slowly in the absence of a catalyst. The active site of most carbonic anhydrases contains a zinc ion; they are therefore classified as metalloenzymes. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012). Chapter 39.
