Physicochemical Properties Used to Predict Cation Binding

5 PHYSICOCHEMICAL PROPERTIES USED TO PREDICT CATION BINDING 

Scale values=-1.68 + Z(1.22 + 0.444PE) R =0.969 Scale of toxicities=a + b(Atomic mass) + cPE, R =0.625 - 0.896 Z= ionic charge, Pii = Pauling electronegativity log A scaie M=values in the scale of relative binding strengths 

Zhou et al. (2011) evaluated 50 conditional binding constants (K) for biotic ligands from 27 studies and calculated mean ligand-specific conditional binding constants (K). They developed log K QSARs for five species using the Pearson and Mawby softeess parameter (a ), the covalent index (x r), the absolute value of
