WebFeb 17, 2024 · Structure of chitin Chitin is a β(1,4)-linked homopolymer of N-acetyl glucosamine derivative of glucose, and it shares close structural similarity to cellulose. In chitin, the alcoholic OH group of the second carbon atom of β-D-glucose units is replaced by an N-acetylamino group. 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 ).
