Chitin is a polysaccharide which is a long chain polymer of N-acetylglucosamine. It is found in the cell walls of fungi and exoskeletons of arthropods such as insects, crustaceans, cephalopod beaks and scales of fish. It has a structure comparable to cellulose. Chitosan is formed by the treatment of chitin cells of crustaceans with an alkaline substance like sodium hydroxide. It is a linear polysaccharide which consists of randomly distributed β-(1→4) linked D-glucosamine and N-acetyl-D-glucosamine. Chitin is used to create edible films in food industry. It is also used as an additive to stabilize and thicken foods and food emulsions. Chitosan is used as a pesticide to fight plant fungal infections. It also finds applications in beverage industry as fining agent and as an antibacterial agent in bandages to help reduce bleeding.
