Chitosan - Wikipedia
网页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. [1][2]
