Web7 sep. 2024 · To determine the pI value for the protein, the pH value at which the charge state of the protein is equal to zero must be found. ... Calculate the pKa with the formula pKa = -log(Ka). For example, pKa = -log(1.82 x 10^-4) = 3.74. What are the differences between pI and pH? WebThe pI for a simple compound can be calculated by averaging the two pKa’s that are relevant to the concentration of the molecule in its neutral charge state. For example, for glutamate: = + 2 = 2.19+4.25 2 =3.22 Since the pI is the pH where the average charge of the molecule in solution is zero, we can verify our calculated pI by calculating ...
