Here are the essential concepts you must grasp in order to answer the question correctly.
Glycosidic Bond
A glycosidic bond is a type of covalent bond that connects two monosaccharides through a dehydration reaction, resulting in the formation of a disaccharide. In cellobiose, this bond specifically links the anomeric carbon of one glucose unit to the hydroxyl group of another glucose unit, creating a β(1→4) linkage.

Disaccharides
Disaccharides are carbohydrates formed by the combination of two monosaccharides through glycosidic bonds. Cellobiose, composed of two glucose molecules, is an example of a disaccharide that plays a significant role in the structure of cellulose, a major component of plant cell walls.

Cellulose
Cellulose is a polysaccharide made up of long chains of β-glucose units linked by β(1→4) glycosidic bonds. It is a key structural component in plant cell walls, providing rigidity and strength. Understanding cellobiose's structure helps in comprehending how cellulose is formed and its importance in biological systems.
