HMG-CoA (or 3-hydroxy-3-methylglutaryl-coenzyme A) is an intermediate in the mevalonate and ketogenesis pathways. It is formed from acetyl CoA and acetoacetyl CoA by HMG-CoA synthase.

It is also an intermediate in the metabolism of leucine. Its immediate precursor is 3-methylglutaconyl CoA.

Mevalonate pathway[edit]

Main article: Mevalonate pathway

HMG-CoA reductase converts it into mevalonic acid.

Mevalonate pathway

Ketogenesis pathway[edit]

HMG-CoA lyase breaks it into acetyl CoA and acetoacetate.
