Uses and synthesis of L-Tryptophan powder

L-Tryptophan was a neutral aromatic amino acid containing indolyl, white or slightly yellow leaf crystal or powder, with a solubility of 1.14 g(25°C) in water, soluble in dilute acid or dilute base, relatively stable in alkaline solution and decomposed in strong acid. L-Tryptophan powder was slightly soluble in ethanol, but insoluble in chloroform and ether.

Applications/Functions of L-Tryptophan powder

• Amino acid drugs. L-Tryptophan powder was used for amino acid infusion. Often used with iron, vitamin, etc., and VB6 combined to improve depression, prevention and treatment of rough skin disease; Used as an insomnia sedative in conjunction with L-dopa to treat Parkinson's disease. Carcinogenic to experimental animals; There are nausea, anorexia, wheezing and other adverse reactions. Do not use with monoamine oxidase inhibitors.
• L-Tryptophan was used for biochemical studies and pharmaceutically as a sedative.
• L-Tryptophan powder was used for the improved cellulase chromatographic separation. As a spacer in serum protein isokinetic electrophoresis, it can meet the growth requirements of various microorganisms
• L-Tryptophan powder could be used to improve the nutrition and enhance the body constitution, for the nutritional and biochemical studies, and for the preparation of tissue media.

Physicochemical Property of L-Tryptophan powder

L-Tryptophan powder was white crystalline powder. Odorless, slightly bitter taste, slightly soluble in water for a long time light will be colored. When heated with water, a small amount of indole is produced. When heated in the presence of sodium hydroxide and copper sulfate, a large amount of indole is produced. The indole is more stable when heated with acids in the dark, but it is easily decomposed when heated with other amino acids, sugars and aldehydes. When proteins are broken down by acid, tryptophan is completely broken down.

Production methodprocess of L-Tryptophan powder

Dl-tryptophan was used as raw material, the chloracetic anhydride was added into the reaction under cooling condition, then ground in ice water after sulfuric acid acidification, recrystallized in water after filtration, and finally treated with pancreatic carboxypeptide to remove D-type, acetic acid acidification, ethanol recrystallization and refining to obtain L-Tryptophan.
