What metabolic intermediate is formed from the carbon skeleton of the amino acid valine?

Question

Quizplus · Accepted Answer

The amino acid valine can be converted into the metabolic intermediate succinyl CoA through a series of reactions in the catabolic pathway known as the branched-chain amino acid metabolism. Valine is converted to isobutyryl CoA and then to methylmalonyl CoA, which can be converted to succinyl CoA through a vitamin-B12-dependent reaction. Therefore, the correct answer is D, succinyl CoA.
