| acetoacetyl-CoA | Intermediate in the oxidation of fatty acids and in the formation of ketone bodies; also formed from two molecules of acetyl-CoA; major role is condensation with acetyl-CoA to form the important beta-hydroxy-beta-methylglutaryl-CoA. Synonym: acetoacetyl-coenzyme A. (05 Mar 2000) |
| acetoacetyl-CoA reductase | An oxidoreductase catalyzing interconversion of a 3-oxoacyl-CoA and NADPH, and the corresponding d-3-hydroxyacyl-CoA, and NADP+. A step in fatty acid synthesis. (05 Mar 2000) |

| acetoacetyl-CoA thiolase | An acetyltransferase forming acetoacetyl-CoA from two molecules of acetyl-CoA, releasing one CoA. A key step in ketogenesis and sterol synthesis. Synonym: acetoacetyl-CoA thiolase, acetyl-CoA thiolase, thiolase. (05 Mar 2000) |
| acetyl-CoA | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |
