Branched-chain α-keto acid dehydrogenase (BCKD) is a multi-enzyme complex responsible for the oxidative decarboxylation of branched-chain amino acids (BCAAs) like leucine, isoleucine, and valine into their corresponding acyl-CoA derivatives. This process is crucial as it connects amino acid metabolism to the citric acid cycle, allowing the body to use these amino acids for energy production and biosynthesis.
