Cellulose is a polymer of:

Cellulose is a polymer of glucose $\beta-\mathrm{D}(+)$ glucose units are attached to each other by $\mathrm{Cl}$ to $\mathrm{C} 4$ bonds through p-glycosidic linkage in structure of cellulose. Related Theory Cellulose is a linear polysaccharide polymer with many glucose monosaccharide units. The acetal linkage is beta which makes it different from starch. This peculiar difference in acetal linkages results in a major difference in digestibility in humans. Fructose is a monosaccharide that is found in fruits and vegetables. They have a fivemembered carbon ring and the general formula is $\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6$. Insulin is a naturally occurring homopolymer of fructose which consists of 3-60 monomers.
