quality
This product is a white or off-white crystalline powder. Odorless or slightly smelly, slightly bitter. Melting point 289 °C (decomposition). Slightly soluble in water (1.14%, 25 °C) and very slightly soluble in ethanol; Dissolve in dilute acid or dilute base. Coloring is done when the light is long in the light. Coheating with water produces a small amount of indole, and if heated in the presence of sodium hydroxide and copper sulfate, a large amount of indole is produced. It is more stable with acid when heated in the dark. It is easy to decompose when it coexists with other amino acids, sugars, and aldehydes. If no hydrocarbons coexist, it is still stable when heated with 5mol of sodium hydroxide to 125 °C. When proteins are broken down with acids, tryptophan is completely broken down, resulting in putrid black.
Tryptophan is a heterocyclic amino acid, which is an essential amino acid. In the body, it can be converted into a variety of physiologically active substances such as serotonin, niacin, melanotensin, pineal hormone and yellow uric acid. When the human body lacks tryptophan, it will not only cause general hypoproteinism, but also produce special diseases such as skin diseases, cataracts, vitreous degeneration and myocardial fibrosis. It also enhances the body's resistance to radiation. The minimum daily requirement for the human body is 0. 2g。
