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-).
Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term carbohydrate is based on its components: carbon (carbo) and water (hydrate). Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.
