For each protein, there is a pH at which negative and positive charges are equal. This pH is referred to as the ___________.
A)pH point
B)neutralization point
C)isometric point
D)isoelectric point
E)isotonic point

Question

Quizplus · Accepted Answer

The isoelectric point is the pH at which the net charge of a protein is zero due to equal numbers of positive and negative charges being present. This occurs because at a specific pH, certain amino acids that make up the protein will carry a positive charge while others carry a negative charge. At the isoelectric point, these charges will cancel out and the protein will have a neutral charge. This is an important property for biochemical studies and protein purification techniques.
