Branched Chain Amino Acid Metabolism | BCAA Catabolism | Pathway and Regulation

The video tutorial explains the metabolism and catabolism of branch chain amino acids (BCAAs) such as valine, isoleucine, and leucine. It covers their essential role in the diet, their metabolic pathways, and the enzymes involved, including branch chain amino transferase and branch chain alpha-ketoacid dehydrogenase. The tutorial also discusses the regulation of these processes and the categorization of BCAAs as glucogenic or ketogenic based on their metabolic products. Key regulatory factors like BDK and PTPN 1K are highlighted, along with the importance of cofactors such as vitamin B6 and B12.
