WebThe isoelectric point is the average of the 2 pKa values that have a neutral molecule as one of its equilibrium species. In other words, find the pKa that takes the amino acid from neutral to -1 (9.60 for glycine), find the pKa value that takes the amino acid from neutral to +1 (2.34 for glycine), and then find the halfway point or average. WebThe isoelectric point (pI) is the pH value at which the molecule carries no electrical charge. The concept is particularly important for zwitterionic molecules such as amino acids, peptides, and proteins. For an amino acid, the isoelectric point is the average of pKa values for the amine and the carboxyl group.
