Oxidation-Reduction Potentials

In the first part of the book purely physico-chemical considerations of redox potentials are lucidly and thoroughly dealt with, and in the second part their applications to physiology are systematically developed. To a student of physiology, who is not well versed in the principles of electrochemistry, this book will be of great value as the author initiates the reader first into those parts of physical chemistry, which are just necessary for a proper understanding of true reversible redox systems of importance in physiology. The reversible redox systems of organisms can be classified into two groups: (1) the negative systems, and (2) the more positive systems. The negative systems include cysteine, glutathione, sugar, echinoclirome, hermidin; ihe more positive include hsemoglobin-oxyhaemoglobin, the physiologically unimportant system of hajmoglobinmethsemoglobin and, the very important cytochrome and Warburg's respiratory ferment. The energy-level, expressed in electric potentials of systems formed of
