Inulin is a polymer of

Options

A. Glucose
B. Galactose
C. Fructose
D. Arabinose.

Answer

**Step-by-Step Solution:**

1. **Understanding Inulin**: Inulin is a type of carbohydrate known as a polysaccharide. It is important to identify what its monomer units are.

2. **Identifying Monomer Units**: Inulin is primarily composed of fructose units. Each fructose unit is a simple sugar that can link together to form a larger molecule.

3. **Linkage Type**: The fructose units in inulin are connected by beta-glycosidic linkages. This type of bond is crucial for the structure and function of inulin.

4. **Occurrence**: Inulin is found naturally in many plants, particularly in the roots and rhizomes. It serves as a storage carbohydrate.

5. **Hydrolysis**: When inulin undergoes hydrolysis, it can be broken down into its monomer units, specifically fructose, through the action of enzymes like inulinase.

6. **Conclusion**: Based on the above points, we can conclude that inulin is a polymer of fructose.

**Final Answer**: Inulin is a polymer of fructose.
