Product Introduction

L tryptophan powder is also known as α-aminoindolyl propionic acid. White to yellow-white crystal powder. Odorless or slightly smelly, it will be colored under long-term light. It is more stable when heated with acid in the dark. It is easily decomposed when it coexists with other amino acids, sugars, and aldehydes. Used as a food fortifier and antioxidant. Also used in medicine and so on. It is synthesized from indole aldehyde. It can also be decomposed and synthesized by trypsin.

Manufacture Way:

The earliest production of L-tryptophan mainly relied on chemical synthesis and protein hydrolysis. With the continuous development of research on the production of tryptophan by microbial methods, people began to use microbial fermentation to produce tryptophan. Now it is practical and in a dominant position.Microbial methods can be roughly divided into microbial fermentation methods and enzymatic conversion methods. In recent years, there have also been studies on the production of tryptophan by direct fermentation and chemical synthesis, and the combination of direct fermentation and transformation. In addition, the application of genetic engineering, enzyme immobilization and high-density culture in microbial breeding and enzyme industry has greatly promoted the industrialization process of direct fermentation and enzymatic production of tryptophan.

Applications:

★For Human

L Tryptophan Powder is a nutritional supplements and antioxidants. Tryptophan is the precursor of the important neurotransmitter 5-hydroxytryptamine in the human body, and it is one of the essential amino acids for the human body; it is used in nutritional supplements for pregnant women and special milk powder for infants; it is used in the treatment of niacin deficiency (pellagra) Medicine; as a sedative, it can regulate mental rhythm and improve sleep.

★For Animals:

Promote animal feed intake, weaken stress response, improve animal sleep, increase fetal and young antibodies, and improve lactation of dairy animals.Reduce the amount of high-quality protein in the diet, save feed costs, reduce the amount of protein feed in the diet, save formula space, etc.

★For Plants:

Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA, and it is ubiquitous in higher plants. Auxin can be synthesized through tryptophan in two ways:

L Tryptophan Powder is first oxidized and deaminated to form indole acetone, and then decarboxylated to form indole acetaldehyde; indole acetaldehyde is finally oxidized to indole acetic acid under the catalysis of the corresponding enzyme;

Tryptophan is first decarboxylated to form tryptamine, which is then oxidatively deaminated to form indoleacetic acid.
