Reaction of fatty acid synthase complex
WebEnzymes and Isolated Reactions: Activities of FA Synthase The first iteration of the sequence catalyzed by this enzyme can be represented by the seven following reactions. In the first reaction acetyl CoA is added to a cysteine -SH group of the condensing enzyme (CE) domain: acetyl CoA + CE-cys-SH -> acetyl-cys-CE + CoASH WebFatty acid synthase FAS is a key enzymatic complex in FA synthesis from acetyl-CoA and malonyl-CoA, in the presence of NADPH, into long-chain saturated FAs 155 and it is expressed at high levels in liver and adipose tissue, but at low levels in other tissues.

Two rounds of this reaction yields diacylglygerol-3-phosphate (phosphatidic acid). After the action of phosphatidate phosphatase, the phosphatidic acid is converted to 1,2-diacylglycerol.
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.
