====== Acetyl-CoA ====== Acetyl-CoA is a molecule that participates in many biochemical reactions in protein, carbohydrate, and lipid metabolism. Its main function is to deliver the [[acetyl]] group to the [[citric acid cycle]] to be oxidized for [[energy]] production ---- The citric acid cycle (CAC)—also known as the Krebs cycle or the TCA cycle (tricarboxylic acid cycle) —is a series of chemical reactions to release stored energy through the oxidation of [[acetyl-CoA]] derived from [[carbohydrate]]s, [[fat]]s, and [[protein]]s.
