"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."http://en.wikipedia.org/wiki/Branched-chain_amino_acids
Kolozzeum verkar dock tycka att det är bättre att dra i sig alla essentiella aminosyror, om vi talar om att optimera proteinsyntesen. Men detta är alltså de tre effektivaste aminosyrorna.
