Molecular Formula: C6H11NO4X2
Molecular weight: 161.16
Appearance: yellowish powder
chitosan (hitosan) is a product of chitin N-deacetylation. Chitin, chitosan, and cellulose have similar chemical structures. Cellulose is a hydroxyl group at the C2 position, and chitin and chitosan are at C2. The positions are replaced by an acetylamino group and an amino group respectively. Chitin and chitosan have many unique properties such as biodegradability, cell affinity and biological effects, especially chitosan with free amino groups, which are among the natural polysaccharides. The only alkaline polysaccharide. 
The amino group in the molecular structure of chitosan is more reactive than the acetylamino group in the chitin molecule, so that the polysaccharide has excellent biological functions and can undergo chemical modification reactions. Therefore, chitosan is considered to be a functional biomaterial with greater application potential than cellulose.
Function & Application
Chitosan is a product of natural polysaccharide chitin with some acetyl groups removed. It has a variety of physiological functions such as biodegradability, biocompatibility, non-toxicity, antibacterial, anti-cancer, lipid-lowering, and immune enhancement. It is widely used in food Additives, textiles, agriculture, environmental protection, beauty and health care, cosmetics, antibacterial agents, medical fibers, medical dressings, artificial tissue materials, drug slow-release materials, biomedical fields, medical absorbable materials, tissue engineering carrier materials, Many fields such as medical and drug development and other daily chemical industries.
Chitosan Usage
1.As a preservative and thickening agent.In the food industry is a natural, non-toxic preservative, flocculant, and can adsorb water cadmium, mercury, copper and other heavy metal ions.
2. Used as industrial wastewater and municipal sewage treatment agent, precipitation agent.Thickening agent, stabilizer, gelling agent, binder.
3. It is also used for anti-mildew of acidic substances, forming a transparent semi-permeable film on the surface.Used for curing products, baking products, bread, oily food, etc.
4. Chitosan is a biocompatible, antibacterial and biodegradable polyelectrolyte with a wide range of biomedical and industrial applications.
