Uses:
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.
4. 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.
5. L-Valine can be used for biochemical research, the preparation of tissue culture media. It also used as amino acids nutritional drugs in medicine.
Function:
1. L-Valine added in lactating sows diets can increase milk yield. Its mechanism is that valine can affect the synthesis of alanine and release of muscle. Valine added in lactating sows diets can elevate the content of alanine in the plasma to accommodate breast tissue demand for glucose raw materials. Then milk yield can be improved. Valine is very important for the production and development of breast. And valine is limiting amino acid of lactating sows protein diets. Valine deficiency can reduce the effect of lysine. Although that adding lysine into lactation pig feed can improve the quality of dietary protein. But it can also result in the lack of valine, thereby affect sow milk yield and piglet weight gain. When the concentration of lysine is at higher level, valine will be the first limiting amino acid.
2. L-Valine can improve animals’ immune function. Valine can promote animal bone cells into mature T cells. Valine deficiency can lower levels of complement C3 and transferrin. It can hinder the growth of the thymus and peripheral lymphoid tissues, and inhibit the growth of acidic and neutral cell. When weaned lack valine, it will cause a decline in the ability of synthesis of specific antibody. If chicks lack valine, the antibody response for newcastle disease virus reduce antibody response.
3. L-Valine can affect animal endocrine levels. Studies have shown that valine that is added in lactating sows and lactating rats diets can increase the concentration of prolactin and growth hormone in plasma.
Description:
L-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.
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.
