What is the Main Function of Pure Tryptophan?

Tryptophan (Tryptophan), also known as β-indolylalanine, chemical formula C11H12N2O2, is one of the essential amino acids for the human body. Appearance is white or light yellow crystal or crystalline powder, odorless, slightly bitter taste. Slightly soluble in water, very slightly soluble in ethanol, insoluble in chloroform, easily soluble in formic acid, soluble in sodium hydroxide test solution or dilute hydrochloric acid. Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA, and it is ubiquitous in higher plants. It is also the precursor of 5-hydroxytryptamine, an important neurotransmitter in the human body.

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.

Supplement L-Tryptophan in feed can offer following benefits for the industry, which have been proven by abundant trials and research.
1.Increase the feed intake.
2.Optimize the amino acid profile in feed, particularly essential amino acid profile
3.Reduce crude protein level in diets without impact on animal growth performance, particularly low protein diets for post-weaned piglets
4.Improve the growth rate, weight gain and feed efficiency.
5.Enhance the overall growth, even under stress conditions for immune system, such as depressed, vaccination and deteriorated hygiene conditions.
6.Save the entire cost of feed.
