Chitosan /ˈkaɪtəsæn/ is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide. Chitosan has a number of commercial and possible biomedical uses. It can b… WebChitosan is a natural cationic polysaccharide composed of randomly distributed N -acetyl- d -glucosamine and β- (1,4)-linked d -glucosamine. Chitosan can be chemically synthesized via alkaline deacetylation from chitin, which is the principal component of the protective cuticles of crustaceans [ 1 ]. Chitosan is biodegradable in vivo by ...
