L Tryptophan also known as β-indolylalanine, is one of the essential amino acids for the human body.
L Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA. It is commonly found in higher plants. It is also the precursor of 5-hydroxytryptamine, an important neurotransmitter in the human body. It can be used for pregnant women. Nutritional supplements and special milk powder for infants are used for niacin deficiency (pellagra). As a tranquilizer, it can regulate mental rhythm and improve sleep. It is also one of the raw materials for compound amino acid infusion.
