BCAAs (Isoleucine, Leucine, Valine)

BCAAs stand for Branched Chain Amino Acids, a general term used for L-isoleucine, L-leucine, and L-valine. BCAAs are proteinogenic essential amino acids and are hydrophobic with low solubility. Foodstuffs such as fish (tuna), pork and chicken eggs contain high BCAAs. BCAAs are also abundant in the human body muscles and they play important roles in strengthening and maintaining the muscle, by regulating production and breakdown of proteins. They are also used to treat cirrhosis for their antagonizing effect on aromatic amino acids contained in the blood.
