Serine: common products include L-serine, D-serine and DL-serine

Serine,  also known as β – hydroxyalanine, with the chemical formula C3H7NO3, is named after its earliest source from silk. Serine is a neutral aliphatic hydroxyl amino acid and a non essential amino acid. It plays a role in the metabolism of fats and fatty acids, as well as in the growth of muscles. It also plays a role in the manufacturing and processing of cell membranes, the synthesis of muscle tissue, and the sheath surrounding nerve cells.

Serine is mainly used in compound amino acid preparations to supplement amino acids. Serine is also an important neurotransmitter. The production methods usually include fermentation, protein hydrolysis extraction, chemical synthesis, biological enzyme method, etc.

Common products include L-serine, D-serine and DL-serine.

L-serine, as a basic amino acid that makes up proteins, is widely used in industries such as medicine, food, and cosmetics. At present, the global market demand for L-serine is 10000t/year. L-serine is a non essential amino acid that is an important precursor involved in the synthesis of intracellular biological substances such as purines, pyrimidines, phospholipids, etc. L-serine is a raw material for compound amino acid infusion and can also be used as a raw material for light chemical industry. In addition, due to its special wetting and moisturizing properties, L-serine is widely used in high-end cosmetics both domestically and internationally.

D-serine is one of the most important D-type amino acids in mammals, accounting for approximately one-third of the total free serine in the body. Research has found that higher animals, including humans, have regionally high concentrations of D-serine in their central nervous system, which plays an important role as a neurotransmitter.
