Biocoordination chemistry. pH-metry titration method during study of biometal complexing with bioligands

Position of bioinorganic chemistry in the system of naturl science, as well as relations between bioinorganic and biocoordination chemistry, were considered. The content of chemical elements in geosphere and biosphere was analyzed. Characteristic features of biometal complexing with bioligands were pointed out. By way of example complex equilibria in solution were studie by the method of pH-metric titration using mathematical simulation. Advantages of the methods totality, when studying biosystems, were emphasized
