Which one of the following compounds is different from the rest?

Options

A. Sucrose
B. Maltose
C. Lactose
D. Glucose

Explanation

To determine which compound is different from the rest, we need to analyze the given options based on their classification as either monosaccharides or disaccharides.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- The compounds mentioned are sucrose, maltose, lactose, and glucose.

2. **Classify Each Compound**:
- **Sucrose**: This is a disaccharide composed of glucose and fructose.
- **Maltose**: This is also a disaccharide made up of two glucose units.
- **Lactose**: This is another disaccharide formed from glucose and galactose.
- **Glucose**: This is a monosaccharide, which is a single sugar unit.

3. **Compare the Classifications**:
- Sucrose, maltose, and lactose are all disaccharides.
- Glucose is the only monosaccharide among the options.

4. **Conclusion**:
- Since glucose is the only monosaccharide and the others are disaccharides, glucose is the compound that is different from the rest.

5. **Final Answer**:
- The compound that is different from the rest is **option D: Glucose**.
