We determined the molecular and packing structure of a chitosan–ZnCl2 complex by X-ray diffraction and linked-atom least-squares. Eight D-glucosamine residues—composed of four chitosan chains with two-fold helical symmetry, and four ZnCl2 molecul

The crystal structures of chitosan-L- and D-lactate salts were studied by X-ray diffraction measurements on fiber diagrams. In each lactate, chitosan took on a different crystalline polymorph depending on the preparation temperature. At low temperatu

Differences in the polymorphism and crystallinity of chitosan were found in membranes prepared by different procedures when examined by X-ray diffraction measurements for four samples of chitosan differing in the degree of polymerization. When an ace

The distribution of d -glucosamine moieties was investigated in partially deacetylated chitins prepared under various conditions but with nearly the same degree of deacetylation in the range of 30–65%. The presence of adjacently located (blocked) d

Crystal structures of two polymorphs of chitosan, tendon (hydrated) and annealed (anhydrous) polymorphs, have been reported. In both crystals, chitosan molecule takes up similar conformation (Type I form) to each other, an extended two-fold helix sta

It was found that regenerated chitin obtained by a concentrated alkali treatment at a low temperature is water soluble. Chitin with 38% deacetylation, obtained by treatment with 15 wt.% NaOH at 10°C for four days, showed very good solubility in wate
