Question

Quizplus · Accepted Answer

The isoelectric point (pI) of an amino acid is the pH at which the amino acid has no net charge. It is calculated as the average of the pKa values of the ionizable groups that are closest in pH, typically the carboxyl and amino groups for non-ionizable side chains.
