HNB Supply chitosan chitin 99% Powder
Chitosan is a product of N-deacetylation of chitin. Chitin, chitosan, and cellulose have similar chemical structures. Cellulose is a hydroxyl group at the C2 position, while chitin and chitosan are replaced by an acetylamino group and an amino group at the C2 position, respectively. Chitin and chitosan have many unique properties such as biodegradability, cell affinity, and biological effects, especially chitosan containing free amino groups, It is the only alkaline polysaccharide among natural polysaccharides.
The amino group in the molecular structure of chitosan is more reactive than the acetylamino group in the molecule of chitin, making the polysaccharide have excellent biological functions and can undergo chemical modification reactions. Therefore, chitosan is considered as a functional biomaterial with greater application potential than cellulose.
Chitin generates positively charged cationic groups in the reaction, which is the only positively charged edible food fiber that exists in nature
