MoKa - pKa modelling
WebPredicting pKa. One of the most important physicochemical properties of small molecules and macromolecules are the dissociation constants for any weakly acidic or basic groups, generally expressed as the pKa of each group. This is a major factor in the pharmacokinetics of drugs and in the interactions of proteins with other molecules. For … WebThe logD prediction algorithm calculates partitioning constants based on the fragmental algorithm of logP for the neutral form and a series of correction factors, while considering the type and position of ionization. LogD is calculated as a function of the distribution of all molecular species, governed by pH as predicted by the pK a.. ACD/LogD offers various … ferris state irc
