How many carbon atoms are present in Acetyl CoA ?

Options

A. 2
B. 6
C. 4
D. 3

Answer

To determine how many carbon atoms are present in Acetyl CoA, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Acetyl CoA**:
Acetyl CoA is a molecule that consists of an acetyl group and coenzyme A. The acetyl group is represented as CH3CO, and coenzyme A is a larger complex molecule that does not contribute to the carbon count of the acetyl moiety.

2. **Identify the Acetyl Group**:
The acetyl group (CH3CO) consists of:
- 1 carbon atom from the methyl group (CH3)
- 1 carbon atom from the carbonyl group (C=O)

3. **Count the Total Carbon Atoms**:
Adding the carbon atoms from the acetyl group:
- 1 (from CH3) + 1 (from CO) = 2 carbon atoms

4. **Conclusion**:
Therefore, the total number of carbon atoms present in Acetyl CoA is 2.

### Final Answer:
The number of carbon atoms present in Acetyl CoA is **2**.
