英语释义

    1. the point or narrow range on a pH scale at which an amphoteric molecule or surface carries no electrical charge, or in which the negative and positive charges are equal resulting in a net zero charge the pH at which an amphoteric molecule will not migrate in an electrical field
    Proteins migrate to the pH region corresponding to their isoelectric point, where they become immobilized because of a zero net charge.
