Description: The three branched-chain amino acids include L-isoleucine, L-leucine, and L-valine. They are referred to as branched-chain because of their chemical structure. They are essential amino acids, meaning that the body cannot manufacture them, so they must be present in the diet. They play a key role in maintaining and building muscle tissue.
