L-Serine is Widely Used in Medicine, Food, Cosmetics and Other Industries:

1) As biochemical reagents and food additives;

2) Nutritional supplements, the main role of skin stratum corneum to maintain moisture, key additives in advanced cosmetics;

3) It can be used for biochemical and nutritional research, and can also be used as a raw material for the synthesis of cycloserine;

4) Serine can promote the metabolism of fat and fatty acid and help maintain the immune system;

5) Synthesize precursors of purine, thymine and choline;

6) It has the function of stabilizing the pH value of eye drops, and is non-irritating after eye drops; it is one of the important natural moisturizing factors (NMF).
