  Chemical properties white crystalline powder.Odourless, taste bitter, slightly soluble in water (1.14%, 25 ℃), hardly soluble in ethanol.Soluble in dilute acid or dilute alkali.Mp289 ℃ (decomposition).Isoelectric point 5.89.[alpha] D + 2.8 (5 mol/L HCl), [alpha] D + 6.2 (0.5 mol/L NaOH).Long time is light color.Together with hot water to produce a small amount of indole, in the presence of sodium hydroxide, copper sulfate, heating, produces indole, abundant with an acid to form a relatively stable heating in the dark, but coexist with other amino acids, sugars, aldehyde when heating is easy to decompose.When using acid decomposing protein and tryptophan decomposition completely.
  Use amino acids.Used for amino acid infusion.Often with iron, vitamins and share with VB6 share improve depression, prevention and treatment of skin disease;As insomnia sedatives with L - dopa is used in the treatment of Parkinson's disease.For experimental animals have carcinogenic;Has the adverse reactions such as nausea, anorexia, xiao sleep.Avoid and monoamine oxidase inhibitors used.
  Use nutritional supplements.
  Egg white protein, fish, corn flour contains tryptophan to restrict such as amino acid, content in rice grain is less.But with lysine, methionine, threonine with amino acids.According to 0.02% of tryptophan and 0.1% lysine add in corn products, can significantly improve the titer of protein.
  Amino acid infusion and comprehensive preparations the important composition of amino acids.To treat niacin deficiency.
  Purpose to improve nutrition, enhance physical fitness.
  Used for biochemical research, medicine, used as a sedative.
