The role of ionization in the appearance of biological activity in different classes of organic compounds is quite significant: for example, ionization can facilitate the appearance of selectivity of action of biologically active compounds, substantially affect their adsorption on the receptor surface, the permeability through the biological membranes, etcl [i]. So it is quite important to know the degree of ionization of biologically active compounds in studying ...
