Application
L- Tryptophan is widely used in fields of medicine, food processing, industry, etc.
L-tryptophan is in plant auxin biosynthesis important precurssubstances, the structure the IAA similar, in higher plant are common. Can through the tryptophan auxin, there are two synthetic ways: (1) tryptophan first oxidation take off ammonia indoles acetone, to form the decarboxylation form indole acetaldehyde; Acetaldehyde in the corresponding of indoles enzyme catalytic oxidation as final indoles acetic acid. (2) tryptophan decarboxylation, which formed first, then by colamine oxidation take off ammonia acid indoles formation.
