Uses and synthesis of Tryptophan powder

Tryptophan powder was a neutral aromatic amino acid containing indolyl, white or slightly yellow leaf crystal or powder with the 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. Tryptophan was slightly soluble in ethanol, but insoluble in chloroform and ether. Tryptophan is a heterocyclic amino acid, which is an essential amino acid. In vivo, it can be converted into a variety of physiological active substances such as 5-hydroxytryptamine, niacin, melanin tensin, pineal hormone and xanthuric acid. When the human body lacks tryptophan, it will not only cause general hypoproteinosis, but also produce special diseases such as skin disorders, cataracts, vitreous degeneration and myocardial fibrosis.

Applications/Functions of Tryptophan powder

1. 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.
2. Tryptophan was used for biochemical research and pharmaceutically as a sedative.
3. Tryptophan can improve nutrition, enhance physical fitness, and be used for nutritional and biochemical studies and preparation of tissue media.

Physicochemical Property of Tryptophan powder

Tryptophan was a white or white-like crystalline powder. Odorless or slightly smelly, slightly bitter. Melting point 289℃ (decomposition). It is slightly soluble in water (1.14%, 25℃) and very slightly soluble in ethanol. Dissolve in a dilute acid or base. Long periods of light color.

Production methodprocess of Tryptophan powder

Dl-tryptophan was used as raw material to prepare Tryptophan powder by adding chloroacetic anhydride in the cooling state, grinding in ice water after sulfuric acid acidification, recrystallization in water after filtration, and finally treating with tryptophan powder to remove D-type, acidification by acetic acid and recrystallization by ethanol.
