X-RAY DIFFRACTION STUDIES OF THE CHITOSAN NATURAL POLYMERS
Shakeel Ahmad Khanday and *Samina Akther
Abstract
Chitin, a β-(1→4)-linked polymer of 2-acetamido-2-deoxy-D-glucose
(N-acetyl-D-glucosamine), is mainly derived from the exoskeletons of
insects, crustaceans and the cell walls of fungi and some algae. A new
method to determine the degree of deacetylation (DD) of α-chitin and
chitosan in the range of 17–94% DD using X-ray powder diffraction
(XRD) is proposed.
Keywords: Chitin, insects, deacetylation, X-ray powder diffraction.
