What is chitosan?

Chitosan is the product of N-deacetylation of chitin. Chitin, chitosan and cellulose have similar chemical structures. Cellulose is hydroxyl at C2 position, and chitin and chitosan are replaced by an acetylamino group and an amino group at C2 position respectively. Chitin and chitosan have many unique properties such as biodegradability, cell affinity and biological effect. Especially chitosan containing free amino group is the only basic polysaccharide in natural chitosan -JIAHE

The amino group in the molecular structure of chitosan has stronger reaction activity than the acetylamino group in chitin, which makes the polysaccharide have excellent biological functions and can carry out chemical modification reactions. Therefore, chitosan is considered as a functional biomaterial with greater application potential than cellulose.

Application of chitosan powder

Chitosan is the product of removing some acetyl groups from natural polysaccharide chitin. It has a variety of physiological functions such as biodegradability, biocompatibility, non toxicity, bacteriostasis, 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 sustained-release materials, gene transduction vectors, biomedical fields, medical absorbable materials, tissue engineering carrier materials, medical and drug development, and other daily chemical industries.
