✦ Synopsis

From titration curves of horse-heart cytochrome C with heavy metals followed by differential pulse polargraphy, the average complex formation constants and differential equilibrium function with the external ligand groups have been determined. The values have been compared with those obtained in the same conditions for bacterium Klebsiella pneumoniae and alga Selenastrum Capricorn&urn. The possibility of adsorption of cytochrome on the mercury has been analysed by alternating current voltammetry and cyclic voltammetry.
