Which one of the following is a polysaccharide

Options

A. Nylon
B. Amylose
C. Ribose
D. Polyethylene

Explanation

**Step-by-Step Solution:**

1. **Understanding Polysaccharides:**
- Polysaccharides are large carbohydrate molecules composed of long chains of monosaccharide units. They serve various functions, including energy storage and structural support in living organisms.

2. **Identifying the Options:**
- The options provided are:
- Nylon
- Amylose
- Ribose
- Polyethylene

3. **Analyzing Each Option:**
- **Nylon:**
- Nylon is a synthetic polymer made from the polymerization of amides. It is not a carbohydrate and therefore not a polysaccharide.
- **Amylose:**
- Amylose is a type of polysaccharide. It is a linear polymer made up of α-D-glucose units linked by glycosidic bonds. It is a component of starch and serves as an energy storage molecule in plants.
- **Ribose:**
- Ribose is a monosaccharide, specifically a five-carbon sugar (pentose). It is not a polysaccharide.
- **Polyethylene:**
- Polyethylene is a synthetic polymer formed through the addition polymerization of ethylene. It is not a carbohydrate and therefore not a polysaccharide.

4. **Conclusion:**
- Among the options, amylose is the only polysaccharide. Therefore, the correct answer is **amylose**.

**Final Answer: Amylose is a polysaccharide.**
