The isoelectric point (pH_IEP) of polyampholytes is the pH at which the polymer exhibits no net charge, balancing its positive and negative charges. This point is important because it dictates the net charge of polyampholyte macromolecules at different pH levels. At pH < pH_IEP, the macromolecules carry a positive charge, while at pH > pH_IEP, they acquire a negative charge. At pH = pH_IEP, polyampholytes are neutral. Under these conditions, they may show minimal viscosity in solutions or lose solubility and precipitate.
