Cellulose is a polymer of:

Cellulose is a natural polymer composed of repeating units of D-glucose, a simple sugar. These glucose molecules are linked together by β(1→4)-glycosidic bonds, forming long, unbranched chains. This structure makes cellulose a primary component of plant cell walls, providing rigidity and strength.

Understanding the Options:

• L-Fructose: A monosaccharide (simple sugar) that is not a building block of cellulose.
• D-Fructose: Another form of fructose, also not involved in the formation of cellulose.
• D-Glucose: The correct monomer of cellulose. Cellulose is a polymer of D-glucose units linked by β(1→4)-glycosidic bonds.
• Amylose: A polysaccharide and a component of starch, consisting of α(1→4)-linked D-glucose units. It is not related to the structure of cellulose.
