Product Description
L-valine is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated ?NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated ?COO? form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. In the genetic code it is encoded by all codons starting with GU, namely GUU, GUC, GUA, and GUG.
Application
L-Valine is an essential amino acid and one of 20 proteinogenic amino acids.
L-Valine cannot be manufactured by the body and must be acquired through diet or supplementation.
L-valine is found in grains, dairy products, mushrooms, meats, peanuts and soy proteins.
L-Valine has been used in studies to attenuate arrhythmias and induce hypotensive effects.
Valine is an amino acid used as a skin-conditioning and odor-masking agent.
It is more commonly used in hair care preparations than in skin care.
