Table 4.

Apparent barrier heights and enthalpy difference for pyruvate binding to LDH•NADH complex.

ΔHOFF, kcal/mole ΔHON, kcal/mole ΔH, kcal/mole
No osmolyte 14.0±0.5 2.0±0.4 12.0±0.4
TMAO, 1 M 17.3±0.5 −3.1±0.4 20.3±0.5
Urea, 1 M 14.1±1.1 4.1±1.1 9.8±1.1

ΔHOFF is the enthalpy barrier derived from k6. ΔHON is the enthalpy barrier derived from k−6. ΔH is the enthalpy difference derived from the Arrhenius behavior of K6 = k6 / k−6.
