WebNov 14, 2024 · Chitin is a polysaccharide made of linked N -acetylglucosamine subunits. It has the chemical formula (C 8 H 13 O 5 N) n. The structure of chitin is most similar to that of cellulose. Its function is most similar to that of keratin. Chitin is a structural component of arthropod exoskeletons, fungi cell walls, mollusk shells, and fish scales. Chitin is a modified polysaccharide that contains nitrogen; it is synthesized from units of N -acetyl- D -glucosamine (to be precise, 2- (acetylamino)-2-deoxy- D -glucose). These units form covalent β- (1→4)-linkages (like the linkages between glucose units forming cellulose ). See more Chitin (C8H13O5N)n (/ˈkaɪtɪn/ KY-tin) is a long-chain polymer of N-acetylglucosamine, an amide derivative of glucose.
