Select the polymer of fructose.

Options

A. Starch
B. Cellulose
C. Glycogen
D. Inulin

Answer

To solve the question "Select the polymer of fructose," we need to analyze the options provided and determine which one is a polymer made from fructose units.

### Step 1: Understand the question
The question asks for a polymer of fructose. A polymer is a large molecule made up of repeating structural units (monomers). In this case, we are looking for a polymer that is specifically made from fructose.

### Step 2: Analyze the options
1. **Starch**: Starch is a carbohydrate made up of glucose units. It consists of two components: amylose and amylopectin, both of which are polymers of glucose.
2. **Cellulose**: Cellulose is also a carbohydrate that is made up of glucose units. It has a different structure than starch, but it is still a polymer of glucose.
3. **Glycogen**: Glycogen is another carbohydrate made up of glucose units. It serves as a storage form of glucose in animals.
4. **Inulin**: Inulin is a carbohydrate that is specifically made up of fructose units. It is a type of fructan and consists of chains of fructose linked together by beta-2,1-glycosidic bonds.

### Step 3: Identify the correct answer
From the analysis, we can see that:
- Starch, cellulose, and glycogen are all polymers of glucose.
- Inulin is the only option that is a polymer of fructose.

Therefore, the correct answer is **Inulin**.

### Final Answer: Inulin (Option 4)
