The ADI is often based upon analyzing toxicological scientific studies to find out the very best ideal experimental exposure dose amount in animal studies that was shown to result in no adverse influence, multiplied by an acceptable basic safety component. In general, a safety factor is meant to deliver an adequate margin of protection for consumers by accounting for variability, like variances in between animals and people and variations in sensitivity amongst people.
Aspects like bond angle pressure from deviations from typical tetrahedral angles, torsional strain from non-staggered conformations, and steric strain from van der Waals repulsion concerning non-bonded atoms all lead to the relative stability of different molecular conformations
