A branched-chain amino acid (BCAA) is an amino acid having aliphatic side-chains with a branch (a carbon atom bound to more than two other carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine and valine.Valine The BCAAs are among the nine essential amino acids for humans, accounting for 35% of the essential amino acids in muscle proteins and 40% of the preformed amino acids required by mammals.
The branched-chain amino acids (BCAAs) are L-leucine, L-isoleucine and L-valine. They are proteins found in your food which your body burns for energy. The body uses BCAAs for promoting the healing of injured tissues, speeding up recovery, and to protect against muscle tissue breakdown during workout. Research has also shown BCAA to be helpful in other areas. Leucine is necessary for wound recovery to skin and bones and helps protect muscles; valine helps promote nitrogen balance essential for muscular development; and isoleucine helps boost energy and is necessary for forming hemoglobin.
