Introduction
L-Threonine is an essential amino acid and the naturally occurring, biologically active form of threonine. DL-Threonine is a racemic mixture containing both L-threonine and D-threonine. Threonine is an important component of balanced animal diets and plays a key role in protein synthesis and various physiological functions.
CAS No.
- L-Threonine: 72-19-5
- DL-Threonine: 80-68-2
Molecular Formula: C₄H₉NO₃
Structural Formula: CH₃-CH(OH)-CH(NH₂)-COOH
Physicochemical Properties
L-Threonine is a white crystalline powder with an odorless and slightly sweet taste. It is soluble in water and practically insoluble in ethanol, ether, and chloroform. It has good stability under normal storage and processing conditions but may decompose under strongly acidic or alkaline conditions.
Application
L-Threonine is widely used as an essential amino acid feed additive in poultry, swine, livestock, and aquaculture nutrition. As an important component of protein synthesis, threonine helps maintain balanced amino acid levels and supports healthy growth and development.
Threonine supplementation can help:
- Support protein synthesis and tissue development
- Promote healthy growth and development
- Optimize dietary amino acid balance
- Improve feed utilization and nutritional efficiency
- Support normal intestinal and immune function
- Contribute to healthy muscle and tissue formation
- Support production performance in poultry and swine
Threonine is particularly important in modern feed formulations where precise amino acid supplementation is used to meet animals’ nutritional requirements and improve overall feed efficiency and production performance.
