Overview[edit] A carbonic anhydrase, or carbonate dehydratase, is a type of enzyme that rapidly catalyzes the conversion of carbon dioxide into a proton and the bicarbonate ion (HCO3-).
The term carbohydrate tells us what they are made of - carbon, hydrogen and oxygen. The carbon is hydrated - or joined with water. This means that there is a very special ratio of 2 hydrogens to every 1 oxygen within a carbohydrate. For example, the formula for sucrose is #C_12H_22O_11#.
