WebRemainder of the pathway: Malonyl-CoA is elongated into fatty acids by the stepwise addition of two-carbon acetyl units by the enzyme fatty acid synthase. Synthesis by this process continues to produce 16:0-acyl … WebThe reaction starts with a trans thioesterification of the acyl primer substrate from ACP to the enzyme. Subsequently, the donor substrate malonyl-ACP is decarboxylated to form a carbanion intermediate, which in the third step attacks C1 of the primer substrate giving rise to an elongated acyl chain.

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. Web3. Biosynthesis of Saturated Fatty Acids - Synthases. Successive molecules of malonyl-CoA are added to the single primer molecule of acetyl-CoA in a sequence of reactions catalysed by multifunctional enzyme complexes, fatty acid synthases (FAS), which can be of three main types.
