The isoelectric pH has been defined as the electrically neutral molecule. "At the isoelectric pH of an amino acid that has two pKa values the net charge is <u>0</u>." Thus, option C is correct.
<h3>What is isoelectric pH?</h3>
The isoelectric pH has been defined as the potential of the hydrogen at which the molecule does not carry a net charge and is said to be electrically neutral. The amino acids at isoelectric pH do not carry a charge.
If there are two pKa values of the amino acid then the amino acid has zero charges as the amino acids are always neutral at the isoelectric point.
Therefore, in option C. the net charge is <u>zero</u>.
