Product Description L- Valine is branched chain amino acid, which is among the 8 kinds of essential amino acids and glycogenic amino acids for human body. It can promote normal growth of body, repair tissue, regulate blood sugar and provide needed energy.  Dissolved in water, almost insoluble in ethanol; The quality standard of L- valine requires content (≥98.0%), moisture (≤0.5%), ash (≤1.5%), PH value (4.5 ~ 7.0), and specific rotation (26.0°~ 29.0°); Physical and chemical properties: white crystalline or crystalline powder, odorless, slightly sweet and bitter. View; L- Valine is an essential amino acid, which can be supplemented by dietary sources.  Its natural food sources include grains, dairy products, fragrant mushrooms, mushrooms, peanuts, soy protein and meat.  Although most people can get enough from their diet, cases of valine deficiency are also common.  When valine is insufficient, the central nervous system function of the brain will be disordered and ataxia will lead to tremor of limbs.
