Product Description

 

Product Description

Introduction:L Threonine was isolated and identified from the hydrolyzed products of fibrin by W. C. Rosein in 1935. It has proved to be the last essential amino acid to be discovered. It is the second or third limiting amino acid of livestock and poultry, and it plays an extremely important physiological role in animals. Such as promoting growth, improving immune function, etc.; Balance the amino acids in the diet, so that the amino acid ratio is closer to the ideal protein, thus reducing the protein content requirements of livestock and poultry feed. Lack of threonine can lead to decreased feed intake, growth retardation, decreased feed utilization, immunosuppression and other symptoms. In recent years, the combined product of lysine and methionine has been widely used in feed, and threonine has gradually become a limiting factor affecting the production performance of animals. Further research on threonine is helpful to effectively guide the production of livestock and poultry.

Function:
Threonine is an essential amino acid that helps the body maintain protein balance. It plays a role in the formation of collagen and elastin. When threonine is combined with aspartic acid and methionine, it can resist fatty liver. Threonine is found in the heart, central nervous system and skeletal muscle and prevents the accumulation of fat in the liver. It boosts the production of antibodies to boost the immune system. Among foods, grains are low in threonine, so vegetarians are prone to threonine deficiency.

Function:
Threonine is an important nutrient fortifying agent that can strengthen cereals, pastries, and dairy products. Like tryptophan, it can restore fatigue and promote growth and development. In medicine, due to the structure of threonine contains hydroxyl group, it has a water-holding effect on human skin, combines with oligosaccharide chain, plays an important role in protecting cell membrane, and promotes phospholipid synthesis and fatty acid oxidation in vivo.
