What's 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.
Tryptophan, also known as β-indolylalanine, is one of the essential amino acids of the human body. Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA, and it is ubiquitous in higher plants.
L-Tryptophan is a very effective agent for positive mood and relaxation. It is widely used in dietary supplement production as it improves neurotransmitter balance and optimizes brain function. The compound is also claimed to help prevent and treat various mood-associated health conditions.
L-Tryptophan is the L-enantiomer of the naturally occurring compound Tryptophan. It is an essential amino acid that serves a vital role in the human body as a precursor to the production of the neurotransmitter serotonin. As an essential amino acid, L-Tryptophan is not produced in the body and must be supplemented through food and other dietary sources. Therefore, L-Tryptophan is classified as a nutraceutical, a micronutrient, and an anti-depressant agent.

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.
L-Tryptophan C11H12N2O2
L-Tryptophan is further identified as having CAS number 73-22-3 and molecular formula C11H12N2O2. Its molecular weight is 204.22 g/mol. Other names used to identify the product include Tryptophan, L Tryptophan Ratiopharm, Levotryptophan, Tryptan, and L-Tryptophane.
Generally, the said compound has a flat taste and a white crystal or powder appearance. It is also soluble in water.
L-Tryptophan powder is available for wholesale purchase at Nutriavenue. It is usually packed in paper drums with two layers of poly bags inside, each paper drum weighing twenty-five kilograms. Different packaging materials may be used upon request of customers.
