Thermodynamic Property Values for Enzyme-catalyzed Reactions

Abstract
This chapter deals with how one can obtain values of thermodynamic properties specifically the apparent equilibrium constant K, the standard molar transformed Gibbs energy change rG, and the standard molar transformed enthalpy change rH for biochemical reactions and, in particular, for enzyme-catalyzed reactions. In addition to direct measurement, these property values can be obtained in a variety of ways: from thermochemical cycle calculations; from tables of standard molar formation properties; by estimation from property values for a chemically similar reaction or substance; by means of estimation by using a group-contribution method; by combining a known value of the standard molar enthalpy change rH and an estimated value for the standard molar entropy change rS in order to obtain the standard molar Gibbs energy change rG for a given reaction; and by use of computational chemistry.Citation
