The citric acid cycle is a key metabolic pathway that unifies carbohydrate, fat, and protein metabolism. The reactions of the cycle are carried out by 8 enzymes that completely oxidize acetate, in the form of acetyl-CoA, into two molecules each of carbon dioxide and water. The citric acid cycle begins with the transfer of a two-carbon acetyl group from acetyl-CoA to the four-carbon acceptor compound (oxaloacetate) to form a six-carbon compound (citrate).
The citric acid cycle consists of 8 chemical reactions. To start, oxaloacetic acid, a four-carbon molecule, combines with acetyl coenzyme A from pyruvate oxidation. The coenzyme A molecule separates, donating the acetyl group to oxaloacetic acid so that it becomes a six-carbon molecule - this is called citric acid.
