The molecule's charge is known as its ionization state. The molecules of a substance can exist in different ionization states simultaneously.
WebLysine, for example, could be represented by the following diagram. At physiological pH, lysine has a net positive charge. Thus, we have to increase the pH of the solution to remove positive charge in order to reach the isoelectric point. The pI for lysine is simply the average of the pK a 's of the two -NH 3 + groups. pI = 9.18 + 10.79 10.0 2
