Assertion : Glutamine contains amide group
Reason : Isoelectric point of glutamine is 7.

Options

A. if both are true with reason being correct explanation
B. both are true but reason is not explanation
C. assertion true but reason is wrong
D. and both are wrong

Answer

To solve the question regarding the assertion and reason about glutamine, we can break down the information step by step.

### Step 1: Analyze the Assertion
**Assertion:** Glutamine contains an amide group.

- Glutamine is classified as an alpha-amino acid. It has a side chain that includes an amide functional group (-CONH2).
- Therefore, the assertion is **true**.

### Step 2: Analyze the Reason
**Reason:** The isoelectric point of glutamine is 7.

- The isoelectric point (pI) of an amino acid is the pH at which the amino acid exists in a neutral form, meaning it has no net charge.
- For glutamine, the isoelectric point is approximately 5.65, not 7.
- Therefore, the reason is **false**.

### Step 3: Conclusion
- Since the assertion is true and the reason is false, the correct option is that the assertion is true, but the reason is wrong.

### Final Answer
The correct option is: **Assertion is true, but reason is wrong.**
