Question

Quizplus · Accepted Answer

The term used to describe the pH at which the concentration of the zwitterionic form (having a net charge of zero) of an amino acid is at a maximum concentration is the isoelectric point (pI). At the isoelectric point, the number of positively charged amino groups (NH3+) equals the number of negatively charged carboxyl groups (COO-), resulting in a net charge of zero.
