A polyglucosamine derived from chitin by deacetylating chitin molecule. It is a cellulose-like polymer located mainly in exoskeletons of arthropods (e.g. crabs, shrimps, lobsters and insects) and squidpen. Chemically and physiologically, the compound can be defined as a dietary polysaccharide fiber which cannot be hydrolyzed by digestive enzymes of humans. The ability of chitosan, a glucosamine polymer formed by deacetylating chitin, is known to interact with hydrophobic compounds such as cholesterol, triglycerides, fatty and bile acids and reduce their absorption or reentry into the mucosal cells of animals and man.


is one of commercial biopolymers that its stability, chemical properties and biocompatibility are useful for many potential applications including pharmacological, biomedical, agricultural, food, and waste treatment products (Hirano S 1990). Biomedical uses of the chitosan include packaging films, periodontal use, drug delivery, anti-oxidant, anti-microbial property, weight-lowering and hypocholesterolemia properties, hemostatic hydrogel and wound healing.
