As an essential amino acid, L-Tryptophan is necessary for normal growth in infants and for nitrogen balance in adults, which cannot be synthesized from more basic substances in humans and other animals, suggesting that it is obtained only by intake of tryptophan or tryptophan-containing proteins for human body, which is particularly plentiful in chocolate, oats, milk, cottage cheese, red meat, eggs, fish, poultry, sesame, almonds, buckwheat, spirulina, and peanuts, etc. It can be used as a nutritional supplement for use as an antidepressant, anxiolytic, and sleep aid. Thus, L-Tryptophan can be used for depression, anxiety, sleep apnea, premenstrual syndrome and many other problems. Besides, it can also be used in managing pain tolerance and managing weight.

Function of L-Tryptophan Cas 73-22-3
1. adrenergic agonist
2. L-tryptophan is an essential amino acid which is necessary for normal growth in infants and for nitrogen balance in adults. It acts as a natural dietary supplement and used as an antidepressant, anxiolytic and sleep aid. It is used as a precursor to niacin, indole alkaloids and serotonin. It acts as an important intrinsic fluorescent probe, which finds to estimate the nature of microenvironment of the tryptophan.
3. tryptophan is one of the 21 amino acids comprising a protein. Tryptophan is a component of the skin's natural moisturizing factors.


Application of L-Tryptophan Cas 73-22-3
Amino acids-type drug:
It can be used in amino acid infusion, being often combined with iron and vitamins. Its co-administration with VB6 can improve depression and prevention/treatment of skin disease; as a sleep sedative, it can be combined with L-dopa for the treatment of Parkinson's disease. It is carcinogenic to experimental animals; it may cause adverse reactions including nausea, anorexia and asthmas. Avoid combination with monoamine oxidase inhibitors.
Nutritional supplements:
Tryptophan contained in egg white protein, fish meat, corn meal and other amino acids are limited; content in cereals such as rice is also low. It can be combined with lysine, methionine and threonine for enhanced amino acids. It can be supplemented to corn product at the content of 0.02% tryptophan and 0.1% lysine, being capable of significantly improving the protein potency.
