1）product description
Chitosan is a product of n-deacetylated chitin. Chitin, chitosan and cellulose have similar chemical structure. Cellulose is hydroxyl at C2 position, chitin and chitosan are replaced by an acetyl 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, which is the only basic polysaccharide in natural polysaccharides.
The amino groups in the chitosan molecular structure are more reactive than the acetylamino groups in the chitin molecule, which makes the polysaccharide have excellent biological functions and can carry out chemical modification reaction. Therefore, chitosan is considered as a functional biomaterial with greater application potential than cellulose.
Chitosan is the product of natural polysaccharide chitin removing part of the acetyl group, with biodegradability, biocompatibility, non-toxicity, antibacterial, anti-cancer, lipid-lowering, immune enhancement and other physiological functions. Widely used in food additives, textile, agriculture, environmental protection, beauty care, cosmetics, antibacterial agent, medical fiber, medical dressings, artificial tissue materials, drug slow release materials, gene transduction carrier, biomedical fields, medical absorbable materials, tissue engineering carrier materials, medical and drug development, and many other fields and other daily-use chemical industry.
