Abstract
A spectrophotometric endpoint assay for determination of branched-chain alpha-keto acids is described. The assay depends on measurement of the NADH produced after addition of branched-chain alpha-keto acid dehydrogenase. Interference by pyruvate and alpha-ketobutyrate was eliminated by pretreating the sample with pyruvate dehydrogenase. The method yielded a peripheral venous plasma value of 59 +/- 5 microM (mean +/- SE) for the branched-chain alpha-keto acids of five overnight fasted healthy humans.Entities:
