L-tryptophan Raw Materials powder L-tryptophan Details
L-tryptophan powder Usage and Synthesis.
L-Tryptophan is an important nutrient that is widely used in the fields of medicine, health products, food and feed.
In the field of medicine, L-tryptophan is used in amino acid injection, essential amino acid drugs and additives for hydrolyzed proteins. In the field of food, L-Tryptophan can strengthen the utilization efficiency of the organism to plant protein.
Adding L-tryptophan to feed can regulate the balance of amino acids in feed and promote the growth of poultry and livestock.The production methods of L-tryptophan include chemical synthesis, protein hydrolysis and microbial method.
Among them, the microbial method has gradually become the mainstream method of L-tryptophan production, because this method has the characteristics of low cost, wide source of raw materials and low environmental pollution, etc.
Uses of L-tryptophan powder.
Amino acid drugs. Used for amino acid infusion. Often combined with iron, vitamins, etc. Combined with VB6 to improve depression, prevention and treatment of rough skin disease; as an insomnia sedative with L-dopa for the treatment of Parkinson's disease. Carcinogenic to experimental animals; nausea, anorexia, croup and other adverse reactions. Avoid combining with monoamine oxidase inhibitors.
In vitro studies of L-tryptophan powder.
Product Method of Bulk L-tryptophan powder.
Take DL-tryptophan as raw material, add chloroacetic anhydride under cooling state to react, after acidification by sulfuric acid, grind in ice water, filter and recrystallize in water, finally treat with pancreatic carboxypeptidase to remove D-type, and refined by acidification by acetic acid and recrystallization by ethanol.
