WebOct 11, 2024 · However, chitin is the most abundant polymer of natural origin . Chitin is an amino polysaccharide. Chemically, chitin is composed of β-1,4 linked 2-(acetylamino)-2-deoxy-d-glucose elements (Figure 4) [4,10,11]. The degree of acetylation is >90%. The overall nitrogen content in chitin is ~7%, while the nitrogen to carbon (N/C) ratio is 0.146. Websoluble in water. In nature, chitin forms complex skeletons that form in a multi-step process. Chitin molecules are synthesized by transglycosylating, membrane-bound enzymes known as chitin synthetase EC 2.4.1.16, which use uridine diphosphate-N-acetylglucosamine (UDPGlcNAc) as a substrate. In fungi, for example, this happens
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 ).
