What is Meant by Isoelectric Point?

The isoelectric point is the pH, at which the molecule does not carry any net electric charge. It means that it is electrically neutral in its statistical mean value. The isoelectric point is represented by pl, pH(l) or IEP. In this, the standard representation is pH(l). The isoelectric point value will affect the solubility of the molecules at the given pH value. Generally, the net electric charge of the molecule is affected by the pH value of its surrounding medium.
