D-(+)-Cellobiose

528-50-7

D-(+)-Cellobiose is a disaccharide composed of two D-glucose units linked by a β-(1,4)-glycosidic bond. It is the repeating unit of cellulose, the most abundant organic polymer on Earth. Cellobiose is not digestible by humans but is a key compound in research for studying the structure and enzymatic degradation of cellulose and for analyzing the activity of cellulase enzymes.
