L-tryptophan

L-Tryptophan is an important precusor substance of auxin biosynthesis in plant. It has the similar structure of IAA. It widely exists in higher plant. There are two ways to synthetic auxin. The first is tryptophan oxidizes and deaminize and form indole acetone,then decarboxylation and form IAAId; Under the corresponding enzymes IAAId oxsidizes indoleacetic acid. The second way is 

decarboxylation and form to tryptamine then tryptamine oxsidize deamination finally forms tryptophan.

Properties: Long periods of light are tinted. A small amount of indole is produced by co-heating with water, and a large amount of indole is produced by heating in the presence of sodium hydroxide and copper sulfate. And acid in the dark heating more stable. And other amino acids, sugars, aldehydes coexistence easily broken down. It is found in burley tobacco leaf and flue gas.
