D-Valine Usage And Synthesis
ValineValine is one kinds of the essential amino acids for human being with the requirement of adult males being 10mg / (kg ? d) (FAO/WHO1973). Being lack of this product can cause neurological disorders, reduction of developmental ability as well as anemia.
Valine is one of the 20 amino acids that form protein with its chemical name being 2-amino-3-methyl-butyric acid. It belongs to branched chain amino acids and is one of the eight kinds of essential amino acids and carbohydrate-producing amino acids of human body. It works together with the other two high-concentration amino acids (leucine and isoleucine) to promote the normal growth of body, tissue repair, regulate blood sugar, and provide the energy needed. When participating in intense physical activity, valine can provide extra energy to the muscles for producing glucose in order to prevent of muscle weakness. It also helps remove excess nitrogen (potentially toxic) from the liver, and transport nitrogen to all of the rest parts of the body.
Valine is an essential amino acid, which means that the human body itself cannot synthesize themselves so that it must be replenished through dietary sources. Its natural food sources include cereals, dairy products, mushrooms, mushrooms, peanuts, soy protein and meat. D-Valine is also found in some actinomyces (such as valeriana). While most people can get sufficient quantities of D-valine from the diet, however, there are still many cases about valine deficiency. Upon being lack of sufficient valine, rats get limb tremors due to disorder of the central nervous system as well as ataxia. Through dissecting slices of brain tissue, it was found about the phenomenon of the red nucleus cell degeneration. Owing to the liver function damage of patients with advanced cirrhosis of the liver, hyperinsulinemia is easy to occur, resulting in the reduction of branched chain amino acids in the blood. The ratio of branched-chain amino acids over aromatic amino acids decreases from 3.0-3.5 (normal body) to 1.0 - 1.5. It is common for using injection of branched chain amino acids such as valine in the treatment of liver failure, and the damage of alcoholism and drug abuse on these organs.
Applications1. D-valine can be used for the synthesis of newly efficient pesticide: pyrethroids permethrin and chlorofluorocarbons amyl because of its own biochemical characteristics. The produced valine insecticide permethrin is a broad-spectrum and promising insecticide acaricide which can have effects of touch-killing and stomach poisoning through inhibiting the activity of related enzyme systems of insects. In this way, it can be used for effectively controlling of major pests including Lepidoptera and Diptera in corps such as cotton, fruit trees, and vegetables. D-valine is also widely used in biomedical research. For example, it can be used to inhibit the growth of fibroblasts, and be applied to the studies on its influence on the morphology and function of pulmonary artery endothelial cells. D-valine are also important raw materials as chiral drugs for example it may be used for the synthesis of antineoplastic drugs, anti-diabetes and its complications drugs. With the expansion of the applications fields as well as market demanding of D-valine, the preparation of D-valine will become a hot research field on amino acid.
2. D-Valine is an important organic chiral source which is mainly used in fields such as chiral pharmaceuticals, chiral additive, and chiral auxiliary and other areas. It can also be used as the chiral source of chiral synthesis in the pharmaceutical industry. As an optically active organic acid, it plays an irreplaceable role in the asymmetric synthesis of certain chiral compounds. It is currently mainly used for the production of new broad-spectrum antibiotic, D-valinol, and valine protective agent during the process of peptide synthesis.
3. D-valine is the intermediates for fluvalinate.
4. It is used as a pharmaceutical raw materials and pharmaceutical intermediates, and can also be used for synthetic sweeteners Alatan.
5. It can also be used for biochemical research.

Chemical PropertiesWhite crystal, m.p.> 295 °C (sublimation), [α] 25 = 27.35°; it is soluble in water and very slightly soluble in ethanol.
Production methods1. DL-Acetyl-methionine is used as the raw material. It undergoes acylase splitting, and further hydrochloric acid acidification to have D-valine crystals precipitated; refined product is finally obtained through recrystallization.
2. The preparation method is to use 2-isopropyl-acetyl ethyl to react with benzene diazonium to get corresponding hydrazine compound, and then further reduce it to valine in zinc-ethanol solution and finally go through chemical or biological split.
Chemical Propertieswhite to off-white crystalline powder
UsageD-Valine is an isomer of the essential amino acid L-Valine. D-Valine has been used as a selective agent in epithelial cells in culture since it inhibits cells that lack the enzyme D-amino acid oxidase . D-Valine has also been shown to inhibit proliferation of contaminating fibroblasts in smooth muscle cells from human myometrium. D-Valine solution showed tumor growth inhibition and improvements of the nutritional status in AH109A hepatoma-bearing rats.
