Product Application of L-ThreonineCAS#72-19-5

Threonine is an important nutritional supplement which could fortify cereals, pastries, dairy products, restore the body as fatigue, and promote growth and development like tryptophan. Due to its structure contained threonine hydroxyl,which could held the water on human skin and combined with the oligosaccharide chains to protect cell membranes. Threonine plays an important role in the body, promoted phospholipid synthesis and fatty acid oxidation in the Medicine field as well.
