WebD-methylmalonyl-CoA is racemized to L-methylmalonyl-CoA by the enzyme D-methylmalonyl racemase and then isomerized to succinyl-CoA, which enters the TCA cycle. The enzyme D-methylmalonyl-CoA mutase catalyzes isomerization, with the cobalamin (vitamin B12) coenzyme adenosylcobalamin required as a cofactor. WebAcetyl-CoA (acetyl coenzyme A) is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism. Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.
