The phrase branched-chain amino acids or BCAA is sometimes used
to refer to the amino acids having aliphatic side-chains that are
non-linear. These are leucine, isoleucine and valine. The
combination of these three essential amino acids make up
approximately 1/3 of skeletal muscle in the human body, and play an
important role in protein synthesis. BCAA’s are currently used
clinically to aid in the recovery of burn victims, as well as for
supplementation for strength athletes.
