Product Description

Product Description
High Quality D-Tryptophan CAS: 153-94-6 Price
L-tryptophan is a neutral aromatic amino acid containing an indole group and is a white crystalline powder. Odorless and slightly bitter in taste, slightly soluble in water (1.14%, 25℃), L-tryptophan can improve nutrition and enhance physical fitness, and is used in nutritional and biochemical research as a nutritional supplement. Tryptophan is a limiting amino acid contained in egg white protein, fish meat, corn flour, etc., and its content is relatively low in grains such as rice. It can be combined with lysine, methionine and threonine for amino acid fortification. Adding 0.02% tryptophan and 0.1% lysine to corn products can significantly increase the protein titer.
