Branched-chain
Branched-chain amino acids (BCAAs) are amino acids with side chains that are non-linear. They include leucine, isoleucine, and valine. 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.
Structure[edit | edit source]
BCAAs have aliphatic side-chains with a branch (a central carbon atom bound to three or more carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine, and valine.
Function[edit | edit source]
BCAAs are used in medicine for a number of purposes. They are used to treat liver disease, improve athletic performance, and prevent muscle wasting in people confined to bed.
Dietary sources[edit | edit source]
BCAAs are found in foods and whole protein supplements. Good sources include meat, dairy products, legumes, and protein supplements.
