Tryptophan , also known as β-indolylalanine, is one of the essential amino acids of the human body. Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA, and it is ubiquitous in higher plants. It is also an important neurotransmitter in the human body-the precursor of serotonin; it can be used in pregnancy. Nutritional supplements for women and special milk powder for infants and young children, used for niacin deficiency (pellagra), as a tranquilizer, can regulate mental rhythms, improve sleep.
