A branched-chain amino acid (BCAA) is an amino acid having aliphatic side-chains with a branch (a central carbon atom bound to three or more carbon atoms).Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine and valine.Non-proteinogenic BCAAs include norvaline and 2-aminoisobutyric acid.ietary BCAA supplementation has been used clinically to aid in the recovery of burn victims. A 2006 paper suggests that the concept of nutrition supplemented with all BCAAs for burns, trauma, and sepsis should be abandoned for a more promising leucine-only-supplemented nutrition that requires further evaluation.
