     Valine, Isoleucine and Leucine are all branched-chain amino acids which can be burned for fuel in the cells to promotes muscle recovery when in balance with each other most effective. Only the L-stereoisomers appear in mammalian protein. They play a role in wound healing and the growth of new tissue. These branched amino-acids are needed to increase the bio-availability of complex carbohydrate intake and are absorbed by the muscle cells for anabolic muscle building activity. Branched amino-acids (Valine, Isoleucine and Leucine ) with tryptophan and phenylalanine (aromatic side chain amino acids) contribute to the structure of protein by the tendency of its side chain composed only of carbon and hydrogen to participate in hydrophobic interactions which determines the tertiary structure of the peptide chain.
