Isoelectric point (pI) can be calculated using the formula, pI = pKa1 + pKa2/ 2 for molecules with two ionizable groups (e.g. amino acids like glycine). The pKa1 of the carboxylic acid group of glycine is 2.34 and pKa2 of the amino group is 9.60, therefore, pI (glycine) = (2.34+9.60)/2 = 5.94. 23 Mar 2022

The isoelectronic point will be halfway between, or the average of, these two pKas, i.e. pI = 1/2 (pKa1 + pKa2).
