The correct answer is: Unbranched chain of glucose molecules linked by β-1, 4 glycosidic bond
Cellulose is the most abundant carbohydrate. Cellulose molecule is composed of 1600 to 6000 glucose molecules joined together. Those polymers form long twisting macromolecules of cellulose. The chains are unbranched and linear. The successive glucose residues are joined together by β-1-4, linkages.
