The reason for chitinto be water insoluble but the N-acetyl-D-glucosamine from which it is made to be water soluble needs to be explained. Concept Introduction: Chitin is a polysaccharide formed from the polymerization of N-acetyl-D-glucosamine units which is linked together by 1 → 4-β-glycosidic linkages . Chitin is similar in structure to cellulose, but each OH group at C-2 of chitin is replaced by NHCOCH 3 .

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
