The elastic moduli E l of the crystalline regions of โฃ-chitin and chitosan in the direction parallel to the chain axis were measured by X-ray diffraction. The E l values were 41 GPa for โฃ-chitin, and 65 GPa for chitosan, respectively, at 20ยฐC. The contracted skeletons of โฃ-chitin and chitosan are th
