Products Usage
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.
L-Valine is used as pharmaceutical raw material or for food supplement.
