Amylopectin is a polymer of

Options

A. `beta`- D glucose
B. `alpha` - D glucose
C. `beta`- D fructose
D. `alpha` - D fructose

Answer

**Step-by-Step Solution:**

1. **Understanding Amylopectin**: Amylopectin is a type of polysaccharide and is one of the two main components of starch, the other being amylose. It is important to recognize that amylopectin is a storage carbohydrate.

2. **Composition of Amylopectin**: Amylopectin is composed of repeating units of glucose. Specifically, it is a polymer made up of D-glucose units.

3. **Structure of Amylopectin**: Amylopectin has a branched structure. It consists of linear chains of glucose linked by alpha-1,4 glycosidic bonds, and branching occurs through alpha-1,6 glycosidic bonds.

4. **Identifying the Correct Option**: Given the options:
- Beta-D-glucose (incorrect)
- Alpha-D-glucose (correct)
- Beta-D-fructose (incorrect)
- Alpha-D-fructose (incorrect)

The correct answer is **Alpha-D-glucose**.

5. **Conclusion**: Therefore, amylopectin is a polymer of **alpha-D-glucose**.
