L-valine belongs to branched-chain amino acids, which are 8 essential amino acids and sugar-producing amino acids. It can promote normal growth of the body, repair tissues, regulate blood sugar, and provide needed energy. Dissolved in water, almost insoluble in ethanol.
【product description】
● L-valine belongs to branched-chain amino acids, which are 8 essential amino acids and sugar-producing amino acids. It can promote normal growth of the body, repair tissues, 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 (≤1.5%), ash content (≤0.5%), pH value (4.5~7.0), specific optical rotation (26.0°-29.0°)
● Physical and chemical properties: white crystal or crystalline powder, odorless, slightly sweet and then bitter, view:
● L-valine is an essential amino acid, which can be supplemented by the human body through dietary sources. Its natural food sources include grains, dairy products, shiitake, mushrooms, peanuts, soy protein, and meat. Although most people can get adequate amounts from their diet, cases of valine deficiency are not uncommon. When valine is insufficient, the function of the central nervous system of the brain will be disturbed, ataxia and tremor of limbs will appear.
