Valine

Valine (Val or V) is an amino acid present in proteins.

Structure of valine

Like all of the amino acids, valine is formed from a COOH group and an NH2group which are component links in peptide bonds. It has a symmetrical branched side chain: CH(CH3)2. It is a non-polar, hydrophobic amino acid.

Function of valine

Valine is an essential amino acid which is not produced by the body and must therefore be obtained from the diet (white cheese, fish, poultry, seeds, lentils, etc.).
