Molecular Structure:
Molecular Formula: C11H12N2O2

L-Tryptophan is a natural anti-depressant, plentiful in protein foods but largely lost through cooking and processing. L-Tryptophan is a naturally occurring amino-acid. It is a precursor for the mood-regulating serotonin the brain neurotransmitter linked with pleasure and fulfilment. L-Tryptophan's is used to alleviate depression, support withdrawal and to aid weight loss. L-Tryptophan plays an important role in our diets, and aging individuals are often in need of it as a supplement.
Tryptophan is a kind of white or a kind of white to yellowish crystalline powder, smell-less or slight smelly, L- type has the bitter taste, the DL- and the D- type have little sweet taste. 289 oC decompounds, slightly soluble in water, does not dissolve in the ethyl: Dissolves in the diluted acid or the diluted alkali, the long time illumination will color up; heat together with water can produce the water a small amount of indole, like when heat up under the sodium hydroxide, the cupric sulfate existence, then will produce massive indole; heats up with the acid in the hidden place will be more stable; when coexist with Medicine bulk drugs, carbohydrate, and aldehyde, it is extremely easy to decompose.
Tryptophan is heterocyclic amino acid, is a kind of important and necessary amino acids for human body. It is widely applied in pharmaceutical and food fields.
