L-Valine Usage And Synthesis
Amino acidsL-Valine is a kind of branched-chain amino acids (BCAA). Animal cannot synthesize it by itself. It must be obtained from the diet to meet their nutritional needs. Therefore L-valine belongs to the essential amino acids.
Amino acids are the basic structural unit of protein synthesis, and the predecessor of other amines that metabolism needs. They are indispensable materials in our life. At present, it is known that there are 20 to 30 amino acids. Some of them can be synthesized in the human body, which are known as non-essential amino acids. And some, called essential amino acids, cannot be synthesized in the human body that should be supplemented from the outside. Mammal cells need twelve essential amino acids: L-arginine, L-cystine, L-histidine, L-leucine, L-isoleucine, L-lysine, L-methionine, L-phenylalanine, L-threonine, L-tryptophan, L-tyrosine, L-valine. These amino acids are all laevoisomer, and some non-essential amino acids of dextroisomer may have inhibitory effect on cultured cells.
L-amino acids can easier to be absorbed than D-amino acids. And the absorption of D, L-methionine has no difference. There is competition between the body transport of amino acids. The transporting of an amino acid can be suppressed by the presence of another amino acid. For example, L-valine and L-methionine can inhibit the absorption of L-leucine. Excessive lysine in dietary can inhibit the absorption of arginine. High concentration (100mM) of L-valine has no effect on the absorption of L-methionine. Because it can be transported through another route.
Content AnalysisAbout 200mg sample is accurately weighed, dissolved in 3ml formic acid and 50ml glacial acetic acid. Add 2 drops of crystal violet test solution (TS-74), then use 0.1mol/L perchloric acid to titrate the solution to green or blue disappear entirely. Each Ml0.1mol/L perchloric acid is equivalent to 11.72mg L-valine (C5H11NO2).
Chemical propertyWhite crystal or crystalline powder, odorless, bitter taste. Soluble in water, solubility in water of 8.85% at 25℃. Almost insoluble in ethanol, ether, acetone. melting point(decomposition point) 315℃, isoelectric point 5.96, [α]25D+28.3 (C = 1-2g/ml, in 5mol/L HCl).
Uses
  • 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.
  • 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.
  • 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.
  • L-Valine can be used for biochemical research, the preparation of tissue culture media. It also used as amino acids nutritional drugs in medicine.

UsesL-Valine is an essential amino acid and one of 20 proteinogenic amino acids. L-Valine cannot be manufactured by the body and must be acquired through diet or supplementation. L-valine is found in grai ns, dairy products, mushrooms, meats, peanuts and soy proteins. L-Valine has been used in studies to attenuate arrhythmias and induce hypotensive effects.
