The pH at which the concentration of the zwitterionic form of an amino acid is at a maximum value is called the _______.

Question

Quizplus · Accepted Answer

The isoelectric point (pI) is the pH at which the amino acid carries no net electrical charge, meaning that the concentration of the zwitterionic form is at a maximum value. This occurs because at the isoelectric point, the acidic and basic groups of the amino acid are present in equal amounts and cancel each other out, resulting in a net charge of zero.
