What is Valine?

Valine is an aliphatic and extremely hydrophobic essential amino acid in humans related to leucine, Valine is found in many proteins, mostly in the interior of globular proteins helping to determine three-dimensional structure. A glycogenic amino acid, valine maintains mental vigor, muscle coordination, and emotional calm. Valine is obtained from soy, cheese, fish, meats and vegetables. Valine supplements are used for muscle growth, tissue repair, and energy. (NCI04)

L-valine is the L-enantiomer of valine. It has a role as a nutraceutical, a micronutrient, a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a pyruvate family amino acid, a proteinogenic amino acid, a valine and a L-alpha-amino acid. It is a conjugate base of a L-valinium. It is a conjugate acid of a L-valinate. It is an enantiomer of a D-valine. It is a tautomer of a L-valine zwitterion. (Source: ChEBI)

Valine functions:

Valine is one of the 20 amino acids that make up protein. Its chemical name is 2-amino-3-methylbutyric acid. It is a branched-chain amino acid. It is also an essential eight amino acids and sugar-generating amino acids for the human body. It is different from the other two high Concentration of amino acids (isoleucine and leucine) work together to promote normal growth of the body, repair tissues, regulate blood sugar, and provide needed energy. When participating in intense physical activity, valine can provide extra energy to the muscles to produce glucose to prevent muscle weakness. It also helps remove excess nitrogen (potential toxins) from the liver and transports the nitrogen needed by the body to various parts.
