Which of the following sugars have the same number of carbon as present in glucose ?

Options

A. Fructose
B. Erythrose
C. Ribulose
D. Ribose

Explanation

To determine which of the following sugars has the same number of carbon atoms as glucose, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number of carbon atoms in glucose**:
- The molecular formula of glucose is C₆H₁₂O₆. From this formula, we can see that glucose contains **6 carbon atoms**.

2. **List the options provided**:
- The question provides several sugar options. For this solution, we will consider the following common sugars:
- Fructose
- Erythrose
- Ribulose
- Ribose

3. **Determine the number of carbon atoms in each sugar**:
- **Fructose**: This sugar has **6 carbon atoms** (C₆H₁₂O₆).
- **Erythrose**: This sugar has **4 carbon atoms** (C₄H₈O₄).
- **Ribulose**: This sugar has **5 carbon atoms** (C₅H₁₀O₅).
- **Ribose**: This sugar also has **5 carbon atoms** (C₅H₁₀O₅).

4. **Compare the number of carbon atoms**:
- Now, we compare the number of carbon atoms in each sugar with that of glucose:
- Fructose: 6 carbon atoms (matches glucose)
- Erythrose: 4 carbon atoms (does not match)
- Ribulose: 5 carbon atoms (does not match)
- Ribose: 5 carbon atoms (does not match)

5. **Conclusion**:
- The only sugar that has the same number of carbon atoms as glucose is **Fructose**.

### Final Answer:
**Fructose** has the same number of carbon atoms as glucose.
