………………….. Is a derived monosaccharide.

Options

A. Glucose
B. Fructose
C. Raffinose
D. Deoxyribose

Explanation

To answer the question, "……………….. Is a derived monosaccharide," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Monosaccharides:**
- Monosaccharides are the simplest form of carbohydrates that cannot be hydrolyzed into simpler sugars. Examples include glucose, fructose, and galactose.

2. **Identify Derived Monosaccharides:**
- Derived monosaccharides are modified forms of monosaccharides. They can be altered through various chemical processes, such as deoxygenation, reduction, or substitution.

3. **Examples of Derived Monosaccharides:**
- Some common examples include:
- **Deoxyribose:** Formed from ribose by the removal of an oxygen atom.
- **Glycerol:** A sugar alcohol derived from monosaccharides.
- **Ascorbic Acid:** A sugar acid derived from glucose.
- **Glucosamine:** An amino sugar where an amino group replaces a hydroxyl group in glucose.

4. **Select the Correct Answer:**
- Among the examples provided, **deoxyribose** is a derived monosaccharide that is specifically formed from ribose by deoxygenation. Therefore, the answer to the question is **deoxyribose**.

### Final Answer:
**Deoxyribose is a derived monosaccharide.**
