L-Valine 99%, CAS 72-18-4

What is L-Valine? L-Valine is one of the essential amino acids. It exists in the leaves and smoke of flue-cured tobacco and burley tobacco. It is one of the branched chain amino acids (BCAA). The important character of L-Valine L-type amino acids are easier to absorb than D-type amino acids. There is competition among the organism?s transportations of amino acids. The transportation of one amino acid could be restrained by the existence of another amino acids. For example, excess lysine in the formula feed will restrain the absorption of arginine. However, L-Valine of high concentration (100mM) does not affect the absorption of L- methionine. This is because L-Valine could be transported by another channel. What does L-Valine do? In recent years, people found out that L-Valine is an important intermediate for synthesizing various APIs and Agricultural chemicals. L-Valine?s annual consumption surges to thousands of tons ever since. For human-beings L-Valine can cure hepatic failure and central nervous system dysfunction. The requisite amount for male adults is 10mg/?kg?d?. The physiological effect of L-Valine is twice as that of D-valine. Lack of L-Valine can cause neurological disorder, arrest of development, weight loss, anemia, etc. As a nutritional supplement, L-Valine can be used for formulating amino acids infusion and synthesis of amino acid preparation with other essential amino acids. In particular, it could be used to formulate high branched chain amino acid infusion (i.e. 3H infusion) and oral liquid (i.e. Liver Ann dry syrup). Moreover, if apply valine (1g/kg) to rice-made pastry, there will be an aroma of sesame. Thus, L-Valine could be applied to bread for taste improvement.
