Branched-chain α-ketoacids are preferentially reaminated and activate protein synthesis in the heart

Branched-chain amino acids (BCAA) and their cognate α-ketoacids (BCKA) are elevated in an array of cardiometabolic diseases. Here we demonstrate that the major metabolic fate of uniformly-(13)C-labeled α-ketoisovalerate ([U-(13)C]KIV) in the heart is reamination to valine. Activation of cardiac bran...
