Branch Chain Amino Acids also known as (BCAAs) are indispensable amino acids whose carbon structures are marked at branched points. They are contained mainly in protein rich foods and make up three out of the eight essential amino acids; Valine, Isoleucine and Leucine. The BCAAs; leucine, Isoleucine and Valine, make up about 1/3 of the muscle protein. They stimulate the protein muscle building and possibly reduce muscle breakdown. BCAAs also play a vital role to prevent faulty message transmission in the brain cells.
