The usage of Gibbs free energy (G) in biochemistry is examined critically. The textbook formulation of the Second Law of Thermodynamics as applied to chemically-reacting systems is reviewed. Cognizance of the established theory and terminology of chemical thermodynamics leads to the conclusion that the symbol "delta G", as used in most biochemical calculations of free-energy change (e.g. in freeze-clamp study of steady-state metabolic processes), is erroneous. The instantaneous change… CONTINUE READING
