WebOne of the most studied oxidation reactions involving pyruvate is a two part reaction involving NAD + and molecule called co-enzyme A, often abbreviated simply as "CoA". This reaction oxidizes pyruvate, leads to a loss of one carbon via decarboxylation, and creates a new molecule called acetyl-CoA. Web8 minutes ago · Researchers identify a short-chain carbon circuit that enables reverse flux of pyruvate-derived acetyl CoA through medium-chain ketothiolase (MKT) to regenerate critical co-factors necessary for β-oxidation of long-chain fatty acids, thereby promoting mitochondrial lipid tolerance. Insufficient MKT flux leads to lipid-induced energy instability …
