WebMar 15, 2024 · Chitin deacetylase (CDA, E.C.3.5.1.41) belongs to the carbohydrate esterase 4 (CE4) superfamily. It participates in the degradation pathway of chitin and has a wide range of substrate specificity. It can catalyze the deacetylation of both chitin oligosaccharides and insoluble chitin [ 22 ]. WebChitin from shrimp shells, a long-chain polymer of a β-1,4 linked N-acetylglucosamine residues, may be used to study its physicochemical properties and role in the formation of arthropod exoskeletons. It may be used to identify and characterize chitinase (s) and chitin deacetylase (s), as a standard to study the structure of chitins from other ...
