Chitosan {poly-[(1→4)-)β-d-glucosamine]}, the deacetylation product of chitin, is considered to be a promising bioresource, because, unlike chitin, it is The resulting salts were studied by X-ray fiber diffraction; salts formed with HNO3, HBr, and HI each gave a distinct pattern that suggested retention of the two-fold, helical conformation of untreated chitosan. Patterns of salts prepared with HF, HCl, and H2SO4 differed substantially, showing helical repeats of 40.73 A. Stereochemical… CONTINUE READING
