L-Valine
Molecular formula : C5H11NO2
MW : 117.15
CAS No. 72-5111-18-4

nature : the white monoclinic crystal or crystalline powder. The temperature of about 315 ° C. Water-soluble, solubility (g / L) : 83.4 0 ° C; 25 ° C 88.5; 50 ° C 96.2; 65 ° C 102.4. Almost insoluble in cold ethanol and ether. A 5% solution of pH 5.5-7.0. The heat, light and air stable, odorless, bitter taste.

Preparation Methods : ISOBUTYRALDEHYDE for raw materials, a variety of methods can be synthesized BNDADA valine. For example isobutylaldehyde with ammonia generation amino-2-butanol, hydrogen cyanide with synthetic amino ISOBUTYRONITRILE before hydrolysis from valine, the racemate of the Resolution also have many means such as acyl-DL--amino acid hydrolysis, reuse and free amino acid N-poor solubility of separation. Fermentation production Valine both L-type, without optical resolution. The fermentation for the production of glutamic acid bacteria Micrococcus, producing ammonia Brevibacterium, Escherichia coli, Bacillus off the gas. Using glucose, urea, salts and other media.

purposes : an essential amino acid. Requirement for adult men 10 mg / (kg · d). L-type physiological effect of D-type two-fold. Lack can cause neurological disorders and stop development, weight loss, anemia and so on. As nutritional supplements, amino acids and other essential amino acid infusion preparation of a common and comprehensive amino acid formulations. Rice cakes system add valine (1g/kg), sesame incense products for the bread can also improve the flavor.
