Chitin linkage
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. Chitin is probably the second most abundant polysaccharide in nature (behind only cellulose); … See more The structure of chitin was determined by Albert Hofmann in 1929.
