Interpretation Introduction

Interpretation: An explanation corresponding to the fact that cellulose is water insoluble by considering its three-dimensional structure is to be stated.

Concept introduction: Carbohydrates are polyhydroxy aldehyde and ketones, with an empirical formula ${\text{C}}_{\text{m}}{\left({\text{H}}_{\text{2}}\text{O}\right)}_{\text{n}}$. Glucose is a monosaccharide (or simple sugar) having a molecular formula of ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}$.

Cellulose is an insoluble complex carbohydrate i.e. polysaccharide consisting of a large number of glucose units. It is a linear polymer of $\text{β-D-glucose}$ and the basic structural component of plant cell walls. It is also an excellent fiber.
