Threonine was discovered by w. C. Ro in the hydrolysate of fibrin in 1935 and proved to be an essential Essential amino acid later discovered. Its chemical name is. α— Amino - β— Hydroxybutyric acid. The Molecular formula is) NH2-CH (C00H) - CHOH-CH3. There are four Stereoisomerism, and only L-type has biological activity.

Main purpose

1. Mainly used as a nutritional supplement. Coheating with glucose can easily generate burnt and chocolate aromas, which have a fragrance enhancing effect. It can also be used for biochemical research.

2. As a feed nutrition fortifier, Threonine is an essential amino acid. Threonine is often added to the feed of juvenile piglets and poultry, which is the second limiting amino acid of pig feed and the third limiting amino acid of poultry feed. Added to feed mainly consisting of grains such as wheat and barley.

3. Nutritional additives, also used for preparing amino acid infusion and comprehensive amino acid preparations.

4. Threonine (L-nenenebb threonine) was separated and identified from the hydrolysate of fibrin by W. C. Rose in 1935. It has been proved to be a later Essential amino acid. It is the second or third limiting amino acid of livestock and poultry, and it has extremely important physiological functions in animals. Such as promoting growth and improving immune function; Balance the amino acids in the diet to make the amino acid ratio closer to the ideal protein, thereby reducing the requirements of livestock and poultry for protein content in the feed. The lack of Threonine can lead to reduced feed intake, growth obstruction, decreased feed utilization, immunosuppression and other symptoms of animals. In recent years, lysine and methionine synthetics have been widely used in feed, and Threonine has gradually become a limiting factor affecting animal production performance. Further research on Threonine will help effectively guide livestock and poultry production.

Threonine (L-nenenebb threonine) is an amino acid that cannot be synthesized by animals themselves but is very needed. It can be used to accurately balance the amino acid composition of feed, meet the needs of animal growth and maintenance, increase weight gain and lean meat rate, and reduce feed meat ratio; It can improve the nutritional value of feed materials with low amino acid digestibility and improve the production performance of low energy feed; It can reduce the level of crude protein in feed, improve the nitrogen utilization rate of feed, and reduce feed costs; It can be used for the breeding and breeding of pigs, chickens, ducks, and advanced aquatic products. L-neneneba threonine is a feed additive produced by deep liquid fermentation and refining of Corn starch and other raw materials based on the principle of bioengineering. Adjustable amino acid balance in feed can promote growth, improve meat quality, improve the nutritional value of feed ingredients with low amino acid digestibility, and produce low protein feed. This helps to save protein resources, reduce feed material costs, reduce nitrogen content in livestock manure and urine, as well as ammonia concentration and release rate in livestock and poultry houses. Widely used for adding piglet feed, breeding pig feed, broiler feed, shrimp feed, and eel feed. [1]

6. In the catabolism of Threonine (L-nenenebb threonine) in the body, it is the amino acid that is directly transformed into other substances through the catalysis of Threonine dehydratase, Threonine dehydrogenase and Threonine Fructose-bisphosphate aldolase without deamination and Transamination, for example, Threonine can be transformed into butyryl coenzyme A, Succinyl-CoA, serine, glycine, etc. In addition, excessive Threonine can improve lysine- α- For the activity of keto Gluconic acid reductase, adding appropriate amount of Threonine in the diet can eliminate the decrease of body weight gain caused by excessive lysine, and the ratio of protein/DNA (DNA), ribonucleic acid (RNA)/DNA in liver and muscle tissue decreases. Adding Threonine can also alleviate the growth inhibition caused by excessive Tryptophan or methionine. It is reported that the absorption of Threonine in chickens is mostly in the duodenum, crop and glandular stomach. After absorption, Threonine is rapidly transformed into liver protein and deposited in the body.
