Web1.4.1.1 Chitosan. Chitosan is a naturally derived biodegradable polymer obtained from chitin (a major component of crustacean exoskeleton and fungi cell wall) [40]. It is cationic in nature and is composed of α-1,4-linked 2-amino 2-deoxy α- d -glucose ( N -acetyl glucosamine) [40,41]. WebIntroduction. Chitosan is the linear polysaccharide of glucosamine and N-acetylglucosamine units joined by β-1,4-glycosidic links and it is obtained by deacetilation of chitin through exposure to NaOH solutions or to the enzyme chitinase. Chitosan and chitin are naturally occurring polymers.
