WebFatty acid biosynthesis occurs through a series of reactions involving fatty acid synthase (FAS), a polypeptide multienzyme complex. The result of this synthesis is a saturated fatty acid with up to 16 carbon atoms (palmitic acid). Longer fatty acids and unsaturated fatty acids result from modifications to fatty acids produced by FAS activity. 1.

WebThe first and foremost controlling step involved in the fatty acid biosynthesis is the production of malonyl-CoA. In the initial reaction, acetyl-CoA is carboxylated to malonyl-CoA in the presence of ATP and acetyl-CoA carboxylase, which calls for bicarbonate as a source of CO 2. This enzyme is crucial for controlling the synthesis of fatty acids. WebThe biosynthesis of fatty acids involves the successive addition of two-carbon units to the growing chain.
