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.
Tryptophan Is A Powdery Solid Product Made From Liquid Glucose Through Microbial Fermentation And Extraction.
Tryptophan (symbol Trp or W encoded by the codon UGG) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Trypophan is also a precursor to the neurotransmitter serotonin and the hormone melatonin.
L-tryptophan is an amino acid, a protein building block that can be found in many plant and animal proteins.
L-tryptophan is called an essential amino acid because the body can’t make it. It must be acquired from food.
