Beta oxidation is the term used to describe a series of reactions that break down a fatty acid into 2 carbon acetyl groups which are associated with Coenzyme A (see figure 12). Unsaturated fatty acids bound in the lipid molecules (TAG or PL) or as free fatty acids are the basic substrate of lipid oxidation. Overview. Two (2) carbon units are removed sequentially with each cycle of beta-oxidation. It is catalyzed by a multienzyme complex called fatty acid synthase.
