Product Details
L-Threonine(CAS#72-19-5) is an essential amino acid involved in a variety of physiological and metabolic functions. It is an important component of structural proteins associated with tooth enamel, collagen, and elastin. L-Threonine also contributes to normal nervous system function and participates in metabolic pathways related to porphyrins and fats. In addition, it has been studied for its potential role in supporting digestive health and managing certain intestinal conditions. L-Threonine may also act as a precursor that contributes to increased glycine availability in the brain.

Product Application
Threonine is an important nutritional supplement that can fortify cereals, pastries, and dairy products, help the body recover from fatigue, and promote growth and development similar to tryptophan. Its hydroxyl-containing structure helps retain water in human skin and interacts with oligosaccharide chains to protect cell membranes. Threonine also plays a vital role in the body by promoting phospholipid synthesis and fatty acid oxidation, with applications in the medical field.
