【L-Valine Usages】
1. Amino acids drugs, nutritional supplements. It can be used as the main component of aminophenol transfusion and synthesize aminophenol. L-Valine is one of the three branched-chain amino acids. It is essential amino acid. It can be used to treat liver failure and central nervous system dysfunction.
2. L-Valine is essential amino acid. The requirement for men is 10mg/(kg·d). Physiological effects of the L-form is 2 times of the D-type. L-Valine deficiency can cause neurological disorders, blastocolysis, loss of weight, anemia and the like. As nutritional supplements, it can be used to prepare aminophenol transfusion and synthesize aminophenol with other essential amino acid infusion. Valine added to metric pastry (1g/kg) can make the products aroma of sesame. L-Valine used in bread can also improve the flavor.
3. L-Valine is the essential amino acid. It can be used as one of pharmaceutical composition of amino acid infusion to synthesize drugs. It also can be used as food additives.
Nutritional supplements. It can be used to prepare aminophenol transfusion and synthesize aminophenol with other essential amino acid infusion.Valine added to metric pastry (1g/kg) can make the products aroma of sesame. L-Valine used in bread can also improve the flavor.
4. L-Valine can be used for biochemical research, the preparation of tissue culture media. It also used as amino acids nutritional drugs in medicine.
