L-Valine CAS No.:72-18-4


CAS No.:72-18-4

Assay:99% HPLC



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.


Main Function:

1. L-Valine can provide additional energy to the muscles to produce glucose, to prevent muscle weakness

2. L-Valine can help remove excess nitrogen from the liver, and help nitrogen transport to all parts of the body needs.

3. L-Valine cab be used as a nutritional supplement, may be co-formulated with other essential amino acid infusion, comprehensive amino acid preparations.



1.For Feed Grade Valine:

L-Valine is an essential and indispensable nutrient for pigs and poultry like lysine, theonine, methionine and tryptophan. In practical European formulas, it is usually considered as the fifth limiting amino acid. As it cannot be sythesized in the body, it needs supplementation from the diets.

L-Valine is a branched chain amino acid along with leucine and isoleucine, involved in many important biological functions. It can help to improve the milk yield for lactating sow and enhance animal's immune.

Besides, Valine can improve the feed conversation rate and amino acid efficacy.


2.For Food Grade Valine:

L- valine is a branched chain amino acid, along with leucine and isoleucine, which are essential to repaire tissue, regular blood glucose and provide energy for human body, especially for vigorous exercise. Therefore, it can be used for sports drink.Besides, Valine can also be used as a food additive in bakery to improve flavor of food.


3.For Medicine Grade Valine:

As one of amino acid infusions, valine can be used to treat some liver disease. Besides, valine is one of the precusor substances for synthesis of new drugs.
