Product Description

high quality L-valine cas 72-18-4
Valine is one of the twenty protein amino acids. Proline is also an essential amino acid from a nutritional point of view. The English name Valine is named after Valerian, and the Chinese name is therefore called valine. Its codons are GUU, GUA, GUC and GUG. It is a non-polar amino acid. In sickle-type red blood cell disease, proline in hemoglobin replaces the hydrophilic amino acid, glutamic acid (Glutamate): because proline is hydrophobic, hemoglobin cannot be correctly folded. Proline is completely electrically neutral, and when its side chain is also neutral, the charge generated by its amino and carboxyl groups is just balanced. This molecule is called zwitterion. Food sources rich in proline are: white cheese, fish, poultry, cattle, peanuts, sesame seeds and lentils.

production method

1. It can be obtained by condensation of 2-aminothiazole with p-nitrobenzenesulfonyl chloride and then reduction.
2. Using isobutyraldehyde as a raw material, there are various methods for synthesizing the racemic proline. For example, isobutyraldehyde and ammonia form aminoisobutanol, and then hydrogen cyanide is synthesized to synthesize aminoisobutyronitrile, and then hydrolyzed to obtain proline. There are also various methods for resolution of racemic forms, such as acyl-DL-amino acid. The enzyme is hydrolyzed and separated by the difference in solubility between the free amino acid and the acylated body. The proline produced by the fermentation method is L-type and does not require optical resolution. The strains of the fermentation method are glutamic acid-producing micrococci, Brevibacterium ammonia-producing bacteria, Escherichia coli, and gas-producing bacteria. A medium such as glucose, urea, or an inorganic salt is used.
3. Fermentation method
4. Tobacco: BU, 22; FC, 21; Synthesis: It can be obtained by hydrolysis and refining of fish protein, etc., or it can be synthesized by chemical methods.


Nutritional supplements. It can be combined with other essential amino acids to prepare amino acid infusion and comprehensive amino acid preparations.
