Valine (abbreviated as Val or V) is anα-amino acid with the chemical formula HO2CCH(NH2)CH(CH3)2. L-Valine is one of20 proteogenic amino acids. Its codons are GUU, GUC, GUA, and GUG. Thisessential amino acid is classified as nonpolar. Along with leucine andisoleucine, valine is a branched-chain amino acid. It is named after the plantvalerian. In sickle-cell disease, valine substitutes for the hydrophilic aminoacid glutamic acid in hemoglobin. Because valine is hydrophobic, the hemoglobindoes not fold correctly.
