L-serine is classified as a non essential amino acid. The body can synthesize sufficient amounts of L-serine to meet its daily needs.
Recent research has shown that L-serine and products of its metabolism are essential for cell proliferation and specific functions of the central nervous system. The findings of altered levels of serine and glycine in patients with psychiatric disorders underscore the importance of L-serine in brain development and function.
Applications:
1. Pharmaceutical raw materials: L-Serine is widely used to configure the third-generation compound amino acid infusion and nutritional supplements, and for the synthesis of a variety of drugs and Serine derivatives. It has the role of stabilizing the pH value of the eye drops, non-irritating to the eyes;
2. Food: L-serine used in sports drinks and diet drinks
3. Feed: L-serine used in animal feed to promote animal growth and development;
