Product Description

L-tryptophan is a neutral aromatic amino acid containing indolyl, white or slightly yellow leaf-like crystals or powder, solubility in water 1.14g (25 ° C), soluble in dilute acid or dilute alkali, in alkali It is stable in liquid and decomposed in strong acid. Slightly soluble in ethanol, insoluble in chloroform and ether. Co-heating with water produces a small amount of indole, and heating in the presence of sodium hydroxide and copper sulfate produces a large amount of indole. It is relatively stable when heated with acid in the dark, but it is extremely stable when heated with other amino acids, sugars, and aldehydes. Easy to decompose. When protein is decomposed with acid, tryptophan is completely decomposed.

Application

1. Nutritional supplements. Tryptophan contained in egg white protein, fish, corn flour, etc. is a limiting amino acid, and the content in grains such as rice is relatively small. It can be combined with lysine, methionine and threonine to strengthen amino acids. 2. L-Tryptophan can improve nutrition and enhance physical fitness, and can be used for nutritional and biochemical research and preparation of tissue culture medium.
