Detailed explanation-1: -An anhydrase is defined as an enzyme that catalyzes the removal of a water molecule from a compound, and so it is this “reverse” reaction that gives carbonic anhydrase its name, because it removes a water molecule from carbonic acid.
Detailed explanation-2: -Carbonic anhydrase (CA; carbonate hydro-lyase, EC 4.2. 1.1) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<–>HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
Detailed explanation-3: -Carbonic anhydrase is an example of lyase which also helps in the breakdown reaction without hydrolysis. Carbonic anhydrase is an enzyme that helps in the conversion of the carbon dioxide and water into carbonic acid without the aid of hydrolysis. It also converts the protons into the bicarbonate ions.
Detailed explanation-4: -Carbonic anhydrase (CA) is a thoroughly studied enzyme. Its primary role is the rapid interconversion of carbon dioxide and bicarbonate in the cells, where carbon dioxide is produced, and in the lungs, where it is released from the blood. At the same time, it regulates pH homeostasis.
