An essential amino acid that is consistent of proteins, especially fibrous proteins. Page Top

One of the three branched chain amino acids. They are called BCAA's because they structurally branch off another chain of atoms instead of forming a line. Studies have shown that BCAA's help to stimulate protein synthesis and inhibit its breakdown, so BCAA's have powerful anabolic and anticatabolic effects on the body. They may also potentiate the release of some anabolic hormones, such as growth hormone. Regular ingestion of BCAA's help to keep the body in a state of postive nitrogen balance. In this state, your body much more readily builds muscle and burns fat. Studies have shown that athletes taking extra BCAA's have shown a loss of more bodyfat than those not taking BCAA's.

An essential amino acid needed for optimal growth in infants and for nitrogen equilibrium in adults.

An essential amino acid in mammals. It contains an aliphatic hydrophobic sidechain. [ see schematic diagram

Valine is one of the 20 proteinogenic amino acids. Nutritionally, valine is also an essential amino acid. It is named after the plant valerian.
