acetoacetyl-CoA

Sign in to save

Also known as 3-acetoacetyl-CoA, acetoacetyl coenzyme A, acetoacetyl-coenzyme a, S-acetoacetyl-coenzyme A, S-acetoacetyl-CoA, 3-Acetoacetyl-CoA, S-Acetoacetyl-coenzym A, Acetoacetyl-Coenzyme A

Acetoacetyl CoA is the precursor of HMG-CoA in the mevalonate pathway, which is essential for cholesterol biosynthesis. It also takes a similar role in the ketone bodies synthesis (ketogenesis) pathway of the liver. In the ketone bodies digestion pathway (in the tissue), it is no longer associated with having HMG-CoA as a product or as a reactant.

It also takes a similar role in the ketone bodies synthesis (ketogenesis) pathway of the liver. In the ketone bodies digestion pathway (in the tissue), it is no longer associated with having HMG-CoA as a product or as a reactant.

It is created from acetyl-CoA, a thioester, which reacts with the enolate of a second molecule of acetyl-CoA in a Claisen condensation reaction, and it is acted upon by HMG-CoA synthase to form HMG-CoA. During the metabolism of leucine, this last reaction is reversed. Some individuals may experience Acetoacetyl-CoA deficiency. This deficiency is classified as a disorder ketone body and isoleucine metabolism that can be inherited. Additional mutations include those with the enzymes within pathways related to Acetoacetyl CoA, including Beta-Ketothiolase deficiency and Mitochondrial 3-hydroxy-3-methylglutaryl-CoA Synthase mutation.
