What is chitin? What is the basic unit of chitin?

Chitin. Also known as chitosan.

It is a structure of N-acetylglucosamine that is polymerized by linking and polymerizing with polysaccharides.

Chitin is a kind of nitrogen-containing polysaccharide biological polymer widely existing in nature, and the main ** is the shell of crustaceans such as shrimp, crabs, insects and the organs of molluscs (such as squid.

cartilage), as well as fungi such as cell walls.

Its reserves occupy the second place among the natural polymers on the earth, and it is estimated that the annual synthesis of natural organisms can reach 11011 tons, second only to cellulose. Chitin, which is generally extracted from shrimp and crab shells, contains about 15% amine group (-NH2) and 85% acetyl group (-Coch3).

Chitin is insoluble in general weak inorganic acids or organic solvents, and insoluble in lye, only soluble in strong inorganic acids. Chitin has strong hygroscopicity, moisturizing effect is also quite good, and has the function of adsorbing heavy metal ions.

Chitin, also known as chitin and chitin, its active ingredient is chitosan (chitosan). In nature, chitin exists in the cells of lower plant fungi and algae, the shells of arthropod shrimps, crabs and insects, and the cell walls of higher plants, and is another important polysaccharide in addition to cellulose. Because the chemical structure of chitin is very similar to that of plant cellulose, chitin is also known as animal fiber.

It is worth mentioning that the shell of arthropods contains quite a lot of inorganic salts, calcium, and proteins in addition to chitin. Chitin must be treated with acid and lye to obtain chitin, and then deacetylated to obtain physiologically active chitosan (chitosan). Therefore, it can be said that the higher the degree of deacetylation of chitin, the higher the concentration of its active ingredient, and the stronger the physiological function of the human body.

The basic unit of chitin is acetylglucosamine, which is a polymer composed of 1000 3000 acetylglucosamine residues linked to each other by 1,4 glycoside chains.

It is part of the biopolymer in the bacterial cell wall and is composed of alternating units of GLCNAC and N-acetylmuramic acid (murnac), lactic acid in murnac.

The residue is cross-linked with the oligopeptide. This hierarchical structure is called peptidoglycan (formerly known as murein).

GLCNAC is a monomeric unit of polymer chitopolysaccharide.

It forms the exoskeleton of arthropods.

and other insects and crustaceans. It is the main component of radulas mollusks, cephalopods in the beak, and most of the fungi in the cell chakra wall.

Polymerizes with glucuronic acid to form hyaluronic acid.

GLCNAC has been reported to be an inhibitor of elastase release in human polymorphonuclear leukocytes (inhibition range 8-17%), but this is much weaker than the inhibitory effect of N-acetylgalactosamine (range 92-100%).

Manufacturing Method: Enzymes made using natural manufacturing methods.

degradation, directly from a few blocks of silver to decompose chitin into oligosaccharides.

NAG, for human hyaluronic acid and chondroitin.

The different stages of the procursor can promote the synthesis of hyaluronic acid and strengthen cartilage tissue.

**Women with dry and rough symptoms had a significant increase in the water content under the left eye and upper arm after 60 days of oral administration of 1000mg oligosaccharide NAG daily; Patients with degenerative knee inflammation were given 1000 mg of oligosaccharide NAG orally every day for eight weeks, which had a significant effect on joint movement pain and tenderness.
