We conclude that this inactivity results from the fact that the H-3 proton is completely ionized at physiological pH, and that in the ionized form it does not biologically resemble the normal non-ionized form. Sharpe: A difference of two units in pK, corresponds to a difference of about 11 kJ (3 kcal) in free energy of ionization. Since both heat and entropy effects may contribute to this difference, it is extremely difficult to discuss the inductive effect rigidly unless pKa measurements have been made over a range of temperatures.
