Tryptophan, also known as β- Indolyl alanine, is one of the essential amino acids for human body. The appearance is white or yellowish crystal or crystalline powder, odorless and slightly bitter. It is slightly soluble in water, very slightly soluble in ethanol, insoluble in chloroform, soluble in formic acid, and soluble in sodium hydroxide test solution or dilute hydrochloric acid.
1. Tryptophan powder can help sleep. Food containing tryptophan can promote the secretion of serotonin and melatonin, and regulate the body clock, so it can help sleep.
2. Tryptophan is a kind of nutrient, which is helpful to the synthesis of nicotinic acid and heme, can significantly increase the antibody in the body during pregnancy, and can also promote the secretion of milk.
3. Tryptophan can enhance body resistance and prevent skin diseases to a certain extent.
Using DL tryptophan as the raw material, chloroacetic anhydride is added under cooling state for reaction. After sulfuric acid acidification, it is milled in ice water, filtered, and recrystallized in water. Finally, it is treated with pancreatic carboxypeptidase to remove the D-type, acidified with acetic acid, and recrystallized with ethanol.
