Xilong Brand Stable Factory Chemical Organic Industry Grade 73-22-3 Amino Acid L-Tryptophan Pharmaceutical/Food/Feed Grade

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.
 

Function:
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.

3.Application: 

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.

Tryptophan at a level to reach the proper ratio of Tryptophan/Lysine as we recommend below, could contribute to the optimal growth performance, weight gain, feed intake and feed efficiency.

One of the key benefits of Tryptophan is that it may help to decrease appetite and reduce symptoms of depression and anxiety. Studies have shown that low levels of Tryptophan in the body may lead to anxiety disorders and depression.
 
It has also been shown that the Serotonin resulting from Tryptophan has a limiting effect on appetite and may help to reduce caloric intake and weight in obese people. Tryptophan is further used to synthesize Niacin, which is used in the processing of carbohydrates and fats.
 
Tryptophan supplementation may also encourage healthy sleep patterns. These benefits seem to be directly related to the release and synthesis of Serotonin and Melatonin. Tryptophan is capable of maintaining a fairly consistent level of Serotonin throughout the day and aids in the production of the proper level of Melatonin at night.
 
This makes Tryptophan distinct from the other well-known Serotonin precursor (and Tryptophan metabolite), 5-HTP. When ingested orally, 5-HTP is not subject to any rate-limiting factors, which means there is no control on how high Serotonin levels may go.
 
Consequently, Tryptophan's effects may be less noticeable than 5-HTP, but with potentially fewer side effects.
 
There are a number of medical conditions which Tryptophan is able to improve. A 2010 study showed that Tryptophan may halt the spread of a common liver condition known as steatohepatitis.
 
Tryptophan may also be capable of improving conditions associated with irritable bowel syndrome (IBS). It has been shown that the less Tryptophan a person has in their body, the more serious the symptoms of this condition can be.
