L Tryptophan:White to yellowish white crystals or crystalline powders. No odor or slight odor, slightly bitter. The melting point is 289 C, and the colouring occurs under long illumination. If heated in the presence of sodium hydroxide and copper sulfate, Tryptophan and acid are stable when heated in dark. It is easy to decompose when it coexists with other amino acids, sugars and aldehydes. If no hydrocarbons coexist, it is stable to co-heat with 5 mol/L sodium hydroxide to 125 C. When protein is decomposed by acid, tryptophan is completely decomposed to form saprophyte. It is slightly soluble in water (1.1g/100ml, 25 C). When protein is decomposed by acid, tryptophan is completely decomposed to form saprophyte. Tryptophan is a heterocyclic amino acid and an essential amino acid. In vivo, it can be transformed into many physiological active substances, such as serotonin, nicotinic acid, melanotensin, pineal hormone and xanthuric acid. When the human body lacks tryptophan, it will not only cause general hypoproteinism, but also produce skin diseases, cataracts, vitreous degeneration and myocardial fibrosis and other special diseases. It also increases the body’s resistance to gamma rays. The minimum daily requirement is 0.2g.

1.L Tryptophan is an important nutrient. 2.L Tryptophan takes part in the renewal of animal blood plasma protein in the body 3.L Tryptophan helps nicotinic acid and the synthesis of hemoglobin. It can significantly increase antibody in pregnant animals baby. 4. L Tryptophan can promote lactation of cows and sows. 5. L Tryptophan is used as control agent of pellagra.

L Tryptophan is the precursor of 5-hydroxytryptamine, an important neurotransmitter, and one of the essential amino acids for human body. It is used in nutritional supplements for pregnant women and special milk powder for infants. It is used in the treatment of nicotinic acid deficiency (pellagra). It is used as a tranquilizer to regulate mental rhythm and improve sleep. Human: Nutritional supplements. Antioxidant.

Animals: Promote animal feeding, weaken stress response, improve animal sleep, but also increase fetal and young antibodies, improve lactation of dairy animals. Reducing the amount of high quality protein in diet, saving feed cost, reducing the amount of protein feed in diet, saving the space of formula, etc.
