Product Description
YANXI factory Supply High Quality Powder Valine/L-valine CAS 72-18-4
Valine is one of the 20 protein amino acids. From a nutritional point of view, valine is also an essential amino acid. The English name Valine is derived from Valerian, and the Chinese name is therefore called valine. Its codons are GUU, GUA, GUC, and GUG. It is a non-polar amino acid. In sickle cell disease, the valine in hemoglobin replaces the hydrophilic amino acid Glutamate: Because valine is hydrophobic, hemoglobin does not fold properly. Valine is completely geoelectrically neutral when its side chain is also neutral and the charge generated by its amino and carboxyl groups is just balanced, and this molecule is called a zwitterion. Food sources rich in valine include cottage cheese, fish, poultry, cattle, peanuts, sesame seeds, and beans.
L-valine is an essential amino acid that is necessary for smooth nervous sysytem and cognitive function. And it is one of the three Branched Chain Amino Acids (BCAAs).
L-valine cannot be produced by the body and must be ingested through foods or supplements.
Amino acids is effective as an appetite suppressant, it benefits insomnia and nervousness, muscles, and .the immune system.
L-valine is the white crystals or crystalline powder, fist slightly sweet taste then slightly bitter taste. Freely soluble in formic acid, soluble in water, practically insoluble in ethanol and ether. And it is an essential amino acid that is necessary for smooth nervous sysytem and cognitive function. It is one of the three Branched China Amino Acids (BCAAs). L-Valine cannot be produced by the body and must be ingested through foods or supplements.Valine can provide additional energy to the muscles to produce glucose, to prevent muscle weakness, and can help remove excess nitrogen from the liver, and help nitrogen transport to all parts of the body needs. Valine can be used as a nutritional supplement, may be co-formulated with other essential amino acid infusion, comprehensive amino acid preparations.

Function
1. L-Valine is an essential amino acid for increasing cognitive function and smoothing nervous system fuction.
2. L-Valine is also needed for muscle metabolism, tissue repair and the maintenance of a proper nitrogen balance in the body.
3. L-Valine is found in very concentrated levels in muscle tissue.
4. L-Valine is also good for correcting the type of amino acid deficiencies that can be caused by drug addiction.
Application
1.For Feed Grade Valine:
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. 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.
