D-(+)-Cellotetraose

Cellotetraose

D-(+)-Cellotetraose is a linear oligosaccharide composed of four D-glucose units linked by β-(1,4)-glycosidic bonds. It is a key structural fragment of cellulose, the most abundant organic polymer on Earth. Cellotetraose is not digestible by humans but is used as a research standard to study the activity of cellulase enzymes, which are crucial for the breakdown of cellulose in applications such as biofuel production and the paper industry.
