Description

Multiple Equilibria in Proteins covers the multiple interactions between small ions and molecules and a protein molecule. The book also deals with the physicochemical mechanisms of this interaction and the information about protein structure and the forces stabilizing that structure. The text discusses the mathematical description of complex formation, the thermodynamic analysis of binding data, and various theoretical models which can be used to describe the phenomena of small molecule-macromolecule interactions. The measurement of complex formation; the binding of neutral molecules; and hydrogen-ion equilibria are also considered. The book further tackles metal-ion binding; the binding of organic ions by proteins; as well as protein-protein interaction. Chemists and biochemists will find the book useful.
