Chitobiose

577-76-4

Chitobiose is a disaccharide composed of two N-acetylglucosamine units linked by a β-(1,4)-glycosidic bond. It is the fundamental repeating unit of chitin, the second most abundant polysaccharide on Earth, which forms the exoskeletons of crustaceans and insects and the cell walls of fungi. Chitobiose is a key compound in research on the breakdown of chitin and the biological activities of its derivatives.
