Amino acids l-serine is one of the naturally occurring proteinogenic amino acids. Its codons are UCU, UCC, UCA, UCG, AGU and AGC. Only the L-stereoisomer appears naturally in proteins. L-serine is not essential to the human diet, since it is synthesized in the body from other metabolites, including glycine. Serine was first obtained from silk protein, a particularly rich source, in 1865. Its name is derived from the Latin for silk, sericum. Serine's structure was established in 1902. By virtue of the hydroxyl group, serine is classified as a polar mino acid.

Functions

.png Amino acids l-serine plays an important role in the catalytic function of many enzymes. Amino acids l-serine has been shown to occur in the active sites of chymotrypsin, trypsin, and many other enzymes. The so-called nerve gases and many substances used in insecticides have been shown to act by combining with a residue of serine in the active site of acetylcholine esterase, inhibiting the enzyme completely. The enzyme acetylcholineesterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions in order to allow the muscle or organ to relax. The result of acetylcholine inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop.

Amino acids l-serine used as a biochemical reagent and food additives, l-serine is used for biochemical research, organization culture medium preparation, medicine used for amino acids on nutrition medicine,Nutritional supplement. 

1. For biochemical reagent and food additive.
2. Nutritional supplement, in cosmetics as skin nutrition additive.
3. Available for biochemical and nutritional research purposes,
but also can be used as synthetic ring serine raw materials.
