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.

Function of L-Tryptophan

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.

Food grade:
1. Antioxidant;
2. Nutritional supplements. Tryptophan is one of the essential amino acids of the human body;
3. Used to improve niacin deficiency.

Feed grade
1: Meet the business needs of animal growth, improve animal production performance;
2: Increase the level of digestible L-tryptophan in the feed;
3: As a nutritional feed additive, non-toxic side residues, and can be used safely in various feeds.

Application of L-Tryptophan

It is recommended to add Tryptophan in diet to achieve the optimal amino acid balance and fulfill the digestible tryptophan requirement of people, animals, especially piglets, sows and poultry etc.
