The heat of the reaction NAD(+)+propan-2-ol=NADH+acetone+H(+) was determined to be 42.5+/-0.6kJ/mol (10.17+/-0.15kcal/mol) from equilibrium measurements at 9-42 degrees C catalysed by yeast alcohol dehydrogenase. With the aid of thermochemical data for acetone and propan-2-ol the values of DeltaH=-29.2kJ/mol (-6.99kcal/mol) and DeltaG(0)=22.1kJ/mol (5.28kcal/mol) are derived for the reduction of NAD (NAD(+)+H(2)=NADH+H(+)). These values are consistent with analogous but less accurate data for the ethanol-acetaldehyde reaction. Thermodynamic data for the reduction of NAD and NADP are summarized.
通过在9至42摄氏度下由酵母醇脱氢酶催化的平衡测量，确定反应NAD(+)+丙醇-2=NADH+丙酮+H(+)的热为42.5±0.6kJ/mol(10.17±0.15kcal/mol)。借助丙酮和丙醇-2的热化学数据，得出还原NAD(NAD(+)+H₂=NADH+H(+))的ΔH=-29.2kJ/mol(-6.99kcal/mol)和ΔG(0)=22.1kJ/mol(5.28kcal/mol)的值。这些值与乙醇-乙醛反应的类似但不太准确的数据一致。总结了还原NAD和NADP的热力学数据。
