Product Information

 

L-Tryptophan CAS:73-22-3 is an aromatic neutral amino acid containing an indole ring, with the chemical formula C₁₁H₁₂N₂O₂. It is an "essential amino acid" that the human body and animals cannot synthesize on their own and must obtain from food. The indole ring in its molecular structure gives it unique physiological activity. It is not only an important raw material for protein synthesis but also a precursor for the synthesis of biologically active substances such as serotonin (which regulates mood and sleep), melatonin (which regulates the biological clock), and niacin. It also possesses good nutritional fortification and physiological regulatory functions. This product is a white or slightly yellowish crystalline powder at room temperature, odorless or with a slight odor, slightly soluble in water, and sparingly soluble in organic solvents such as ethanol and ether. It is widely used in feed, food, medicine, and health products, and is one of the core raw materials with both nutritional and physiological functions.

 

L-tryptophan, as an "essential amino acid," derives its core value from providing essential nutritional support to humans and animals and participating in the regulation of key physiological processes. Currently, the animal feed industry is its most important application area, accounting for over 75% of global consumption; however, with increasing emphasis on nutrition and health, its applications in the food, pharmaceutical, and health supplement sectors are gradually increasing, and market demand continues to grow.

Uses and Applications

 

1. Feed Industry: Core Nutritional Fortifier (Core Application Area)

In livestock and aquaculture, the L-tryptophan content in corn-soybean meal-based feeds is generally insufficient to meet the growth needs of animals. Adding L-tryptophan can balance the amino acid composition of the feed, improve its nutritional value, promote animal growth, and reduce breeding costs. It is an indispensable core nutritional fortifier in the feed industry.

 

2. Food Sector: Nutritional Fortifiers and Food Additives

As a food nutritional fortifier permitted for use in China (GB 14880-2012), L-tryptophan can be used to fortify various foods, supplementing essential amino acids for the human body. It can also be used as a flavoring agent to improve food taste and is widely used in infant formula, health foods, dairy products, and condiments.

 

3. Pharmaceutical Field: Pharmaceutical Raw Materials and Excipients

High-purity L-tryptophan, due to its excellent physiological activity and safety, has become an important raw material in the pharmaceutical field. It can be used in amino acid infusions, drug synthesis, and health supplement formulations, playing a significant role in disease treatment and health management.

 

4. Other Fields

- Cosmetics: Used as a cosmetic additive in skincare products, hair conditioners, etc.; it can promote skin cell metabolism, enhance skin elasticity, and improve dry and rough skin; in hair conditioners, it can repair damaged hair, improving hair smoothness and shine;

- Biochemical Engineering: Used as a component of microbial culture media for bacterial culture and biological fermentation processes; it provides essential amino acid nutrients for microbial growth and improves fermentation efficiency;

- Scientific Research: As a commonly used laboratory reagent, it is widely applied in scientific research experiments in fields such as biochemistry, molecular biology, and nutrition, such as research on protein synthesis mechanisms and amino acid metabolism.
