Chitin is the second largest biological resource after cellulose in nature. It is called animal cellulose.

Gold chitosan professional chitosan oligosaccharides say chitin, we must first say sugar substances, sugar is in addition to protein and nucleic acid, another very important class of life substances, sugar chemistry in life sciences, pharmaceutical research occupies an important position and a wide range of uses, we are exposed to more monosaccharide glucose and disaccharide fructose, sugarcane Sugar and so on. Chitin is also a kind of polysaccharide. It is the only natural macromolecule polymer with positive charge in nature. It belongs to linear amino polysaccharide, also known as glucosamine. It has magical function. Chitin is the only amino polysaccharide in nature. The chemical structure of chitin is very similar to that of cellulose, which is widespread in plants. The difference is that if the hydroxyl group (OH) on the second carbon atom of the glucose molecule, the single molecule that makes up the cellulose, is replaced by acetamide (NHCOH3) or amino group (NH2), the cellulose becomes chitin in this sense. Chitin can be said to be animal fiber. Chitin is also a general term, including a variety of similar structures of substances, as a polysaccharide substance chitin has high biocompatibility and safety.

Chitin is widely found in the shells of higher fungi, arthropods, shrimps, crabs and insects. Gold shell professional chitosan oligosaccharides remind that due to the strong hydrogen bonding between macromolecules, chitin in nature has a strong crystalline structure, generally not melting, but also insoluble in water, acid and alkali and general organic solvents, chemical properties are very stable, application is limited, only processed chitin can be widely used.
