Cellotetraose

Cellotetraose is an oligosaccharide composed of four beta(1->4) linked glucose units. It is a derivative of cellulose, a major component of plant cell walls. In cellotetraose, the repeating unit is cellobiose, which itself consists of two glucose molecules linked by a beta(1->4) glycosidic bond. Therefore, cellotetraose can be visualized as two cellobiose units linked together.

This compound is one of the constituent oligosaccharides released during the enzymatic hydrolysis of cellulose by cellulases. Its structure makes it a substrate for certain enzymes involved in carbohydrate metabolism. While not as abundant as cellulose itself, cellotetraose plays a role in the breakdown and utilization of plant biomass.

Cellotetraose has a molecular formula of C24H42O21 and a molar mass of approximately 666.58 g/mol. It is a water-soluble carbohydrate that can be purified and studied to understand the enzymatic processes involved in cellulose degradation. Research into cellotetraose and other cellooligosaccharides is important for fields such as biofuels, enzyme technology, and understanding plant biology.
