The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Starch Composition:** Starch is a carbohydrate that is primarily composed of two types of polysaccharides. These polysaccharides are polymers made from the monomer alpha-glucose. 2. **Identifying the Types of Polysaccharides:** The two types of polysaccharides that make up starch are: - **Amylose:** This is the straight-chain form of starch. - **Amylopectin:** This is the branched form of starch. 3. **Properties of Amylose and Amylopectin:** - Amylose is typically hydrophilic, meaning it can interact well with water. - Amylopectin, while also a polysaccharide, has a branched structure and is generally considered more hydrophobic compared to amylose. 4. **Conclusion:** Therefore, starch is a mixture of amylose and amylopectin. **Final Answer:** Starch is a mixture of amylose and amylopectin. ---
