L-threonine is an important nutritional fortifier that can strengthen grains, pastries, and dairy products. Like tryptophan, it has the effect of restoring fatigue and promoting growth and development in the human body.
In medicine, due to the presence of hydroxyl groups in the structure of L-threonine, it has a water holding effect on the human skin, binds to oligosaccharides, plays an important role in protecting cell membranes, and can promote phospholipid synthesis and fatty acid oxidation in the body.
