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

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false

Correct answer

C. If assertion is true but reason is false

Step-by-step solution

Glutamine is one of the 20 amino acids. Its side chain is an amide formed by replacing the side chain hydroxyl of glutamic acid with an amine functional group, making it the amide of glutamic acid. In human blood, glutamine is the most abundant free amino acid. The isoelectric point is the pH at which a particular molecule or surface carries no net electrical charge. The isoelectric point ( pH ) of glutamine is 5.65.
