Verified step by step guidance

Understand the question: The problem is asking about a structural feature shared by cellulose and glycogen. This requires analyzing their molecular structures and identifying common characteristics.

Recall the structure of cellulose: Cellulose is a polysaccharide composed of β-D-glucose monomers linked by β(1→4) glycosidic bonds. It forms long, linear chains that are insoluble in water and not branched.

Recall the structure of glycogen: Glycogen is a polysaccharide composed of α-D-glucose monomers. It has α(1→4) glycosidic bonds in the linear chains and α(1→6) glycosidic bonds at the branch points, making it highly branched and soluble in water.

Compare the two structures: While cellulose and glycogen differ in solubility, branching, and glycosidic linkages, they share the feature of being polymers of glucose. Both are composed of repeating glucose monomers, though the type of glycosidic bond differs.

Conclude the shared feature: The structural feature shared by both cellulose and glycogen is that they are polymers of glucose, even though their specific structures and properties differ significantly.
