Sigma Aldrich - C8286

Biochem/physiol Actions
Cellotetraose is a substrate for many cellulases and for 1,4-β-D-glucan glucohydrolases. It is also the end product of some cellulases, such as Cel9R from Clostridium thermocellum.
Application
Cellotetraose is a 4-glucose polymer cellulodextrin derived from cellulose degradation. Cellotetraose and other cellulodextrins, such as cellulobiose, cellulotriose and cellopentaose are used by cellulosic bacteria as sources of energy. Cellotetraose is used to help identify, differentiate and characterize oligosaccharide metabolizing enzymes.
