Product Description

Product Description

 
1.  What is L-Tryptophan?
 

Tryptophan is one of essential amino acids and the fourth limiting amino acid in animal diets, which means it could not be synthesized by the body, in addition, dietary supply through feed materials is usually insufficient.

The deficiency of L-Tryptophan was generally characterized as decreased feed intake and efficiency, and slow growth rate. Considering L-Tryptophan playing a key role in growth performance and feed efficiency, it is recommended to add L-Tryptophan in diet to achieve the optimal amino acid balance and fulfill the digestible tryptophan requirement of animals, especially piglets, sows and poultry etc.

Application

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.
