Molecular Formula: C5H11NO2 Molecular Weight: 117.15
Molecular Structure:
Property:
The density of L-Valine is1.23 and the melting point is 315℃. The alpha of
L-Valine is 28 º (c=8, 6N HCl)l and the water solubility is 85 g/L (20 ºC).
Valine (abbreviated as Val or V) is an α-amino acid with the chemical formula HO2CCH(NH2)CH(CH3)2.
L-Valine is one of 20 proteinogenic amino acids. Its codons are GUU, GUC, GUA, and GUG. This essential amino acid is classified as non-polar. Human dietary sources include cottage cheese, fish, poultry, peanuts, sesame seeds, and lentils.
Along with Leucine and Isoleucine, Valine is a branched-chain amino acid.
Valine is named after the plant valerian. In sickle-cell disease,
Valine substitutes for the Hydrophilic Amino Acid Glutamic Acid in hemoglobin. Because
Valine is hydrophobic, the hemoglobin does not fold correctly.
