The carbonic anhydrases (or carbonate dehydratases) (EC 4.2.1.1) form a family of enzymes that catalyze the interconversion between carbon dioxide and water and the dissociated ions of carbonic acid (i.e. bicarbonate and hydrogen ions). The active site of most carbonic anhydrases contains a zinc ion. … See more Carbonic anhydrase was initially found in the red blood cells of cows in 1933 and was simultaneously discovered by Rougton in Cambridge and Meldrum in Philadelphia who were searching for a catalytic factor.

WebAn acid anhydride is a type of chemical compound derived by the removal of water molecules from an acid . In organic chemistry, organic acid anhydrides contain the functional group R (CO)O (CO)R'. Organic acid anhydrides often form when one equivalent of water is removed from two equivalents of an organic acid in a dehydration reaction . WebAug 12, 2024 · Carbonic acid is the product of an acid anhydride reaction between carbon dioxide and water. This reaction can be reversed, or carbonic acid can decompose into water and carbon dioxide. Especially at the high temperatures inside a baking cake, this decomposition will happen, and produce carbon dioxide gas.
