N2 - The acid dissociation constant of haemin has been determined in the temperature range of 0-30 °C. ΔG°, ΔH° and ΔS° of the dissociation are 11.4 kcal/mole, 5.0 kcal/mole and -21 cal/degree per mole, respectively (25 °C). These values are close to the corresponding changes in ferric haemoproteins and differ substantially from those in Fe3+. The significance of this result is discussed.
