note

41 Lacking any estimate of the difference in transition state energies, we have not adjusted any of our values to take these changes into account. Although halving the rate constants would double the half-lives, the prolongation would not alter our conclusions regarding the nil consequences of the 40120 chirality. On the timescale of pharmaceutical development, a half-life increase to 3.2 min at 37°C would be insignificant. Adding the RTln2 term to the Gibbs free energies of activation would increase them only by about 2%.
