China H&Z® L-Serine plays an important role in the catalytic function of many enzymes. It 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.

L-Serine CAS NO:56-45-1 Introduction
L-Serine, also known as beta-hydroxyalanine, is a non-essential amino acid that plays a role in the metabolism of fats and fatty acids and the growth of muscles because it helps in the production of immune hemoglobin and antibodies and maintains a healthy immune system. Serine is also required.
L-Serine plays a role in the production and processing of cell membranes, the synthesis of muscle tissue and sheaths surrounding nerve cells.

L-Serine CAS NO:56-45-1 Function
1.H&Z® L-Serine is a non-essential amino acid rich in eggs, fish, and soybeans. The human body can also synthesize serine from glycine.
2. L-Serine has a wide range of uses in medicine. Serine promotes the metabolism of fats and fatty acids and helps maintain the immune system.
3.L-Serine can be obtained from soybeans, wine starters, dairy products, eggs, fish, milk albumin, pods, meat, nuts, seafood, seeds, whey, and whole wheat. If necessary, the body will synthesize serine from glycine.
L-Serine CAS NO:56-45-1 Application
1.Pharmaceutical field
L- serine widely used to configure the third-generation compound amino acid infusion and nutritionalb supplements, and for the synthesis of a variety of silk amino acid derivatives, such as cardiovascular, cancer, AIDS and genetic engineering of new drugs and other protected amino acids;
2.Food and beverage Field
