In April we had some discussion under the above heading.
Since then I have come across a new paper in Biochemical Education that
contains a large amount of data likely to be useful for calculating the
equilibrium constants of biochemical reactions under physiological
conditions. The reference is as follows:
R. A. Alberty (2000) "Calculating apparent equilibrium constants of
enzyme-catalyzed reactions at pH 7" Biochem. Educ. 28, 12-17.
Table 1 (p. 14) contains standard transformed Gibbs energies of formation
of about 140 biochemical species at 25°C, pH 7 and three different ionic
strengths (0, 0.10 and 0.25). The text includes several examples showing
how one can use the tabulated data to calculate equilibrium constants for
specific enzyme-catalysed reactions.
