| description | 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. |
