Physicochemical characterization of α‐chitin, β‐chitin, and γ‐chitin separated from natural resources

Abstract We isolated α‐chitin, β‐chitin, and γ‐chitin from natural resources by a chemical method to investigate the crystalline structure of chitin. Its characteristics were identified with Fourier transform infrared (FTIR) and solid‐state cross‐polarization/magic‐angle‐spinning (CP–MAS) 13 C NMR s... View More
