title: Measurement of branched-chain alpha-keto acid dehydrogenase flux rates in perfused heart and liver.
abstract: The methods described here represent a flexible set of procedures for investigating the metabolism of the branched-chain alpha-keto acids and other substances in perfused organs, notably the rat heart and liver. These procedures have been used to investigate many aspects of the metabolism of the branched-chain alpha-keto acids not discussed here, such as the effects on branched-chain alpha-keto acid metabolism by exposure to alpha-adrenergic agents, by inhibition of the monocarboxylate translocator, and by the coinfusion of other metabolites.
