Verified step by step guidance

Examine the structure of the disaccharide. Notice that it consists of two monosaccharide units linked together by a glycosidic bond.

Identify the type of monosaccharides present. The left monosaccharide is a glucose unit, and the right monosaccharide is also a glucose unit.

Observe the glycosidic linkage between the two glucose units. It is a beta-1,4-glycosidic bond, as indicated by the oxygen bridge connecting the first carbon of the left glucose to the fourth carbon of the right glucose.

Recall that a disaccharide with two glucose units linked by a beta-1,4-glycosidic bond is known as cellobiose.

Compare the structure to the options provided: Cellulose, Sucrose, Lactose, Maltose, and Cellobiose. The structure matches the description of Cellobiose.
