Which of the following is the best representation of glutamate in an aqueous solution at pH = 1?

Question

Quizplus · Accepted Answer

At pH = 1, glutamate will be in its fully protonated form as the carboxyl group (COOH) will be protonated to form COOH2+ and the amino group (NH2) will be protonated to form NH3+. This is represented in option B where both the COOH and NH2 groups have an extra hydrogen ion attached to them. The other options show incorrect representations of glutamate at this pH.
