Charge Transfer Complexes in Biological Systems


Book Description

Examining the role played by partial charge transfer in biology, this work offers a theroetical basis of the physics and chemistry of charge transfer complex formation, especially the function of excited states. It discusses drug interactions, highlighting interaction between different types of antibiotics and suggests ways for the synthesis of pharmaceutical products with reduced side effects.




Charge Transfer Processes in Condensed Media


Book Description

Molecules in liquid and solid media are exposed to strong inter action forces from the surrounding medium. The formulation of a comprehensive theory of chemical processes in condensed media is consequently an elaborate task involving concepts from several areas of the natural sciences. Within the las~ two and a half decades very notable results towards the formulation of a 'unified' quantum mechanical theory of such processes have in fact been achieved, and by the variety of physical, chemical, and biological processes which can be suitably covered by this framework, the new theory represents an adequate alternative to the transition state theory. The present work has a two-fold purpose. Firstly, to provide a reasonably organized exposition of some basic aspects of these developments. This part emphasizes the fundamental similarities between chemical and other kinds of radiationless processes and includes the derivation of the most important rate expressions without resorting to involved mathematical techniques. The s- ond major purpose is to illustrate the 'unified' character of the rate theory by analysis of a considerable amount of expe- mental data from both 'conventional' kinetics and from such untraditional areas as low-temperature, strongly exothermic, and biological processes. Particular attention is here given to those systems for which a classical description is inadequate, and which provide a diagnostic distinction between several alternative theoretical approaches.

Electron Transfer in Inorganic, Organic, and Biological Systems


Book Description

Developed from a symposium sponsored by the International Chemical Congress of Pacific Basin Societies, Honolulu, Hawaii, December 17-22, 1989.










Bioelectronics


Book Description

Bioelectronics: A Study in Cellular Regulations, Defense, and Cancer examines biological reactions on the electronic level. Chapters in the book discuss topics on the ionization potential and electron affinity; the charge transfer reactions; defense mechanisms of living organisms; and the description of the mechanisms governing the growth and proliferation of cancer cells. Biochemists, oncologists, pharmacologists, and pharmaceutical researchers will find the book invaluable.




Electron Transfer in Chemistry, Principles, Theories, Methods, and Techniques


Book Description

Electron transfer is the most important process to take place in natural and artificial chemical systems, playing a fundamental role, for example, in photosynthesis as well as in photography. Electron transfer reactions - oxidations and reductions - are involved in, among others, a variety of energy conversion processes, analytical methods, synthetic strategies, and information processing systems. This five-volume work is the only comprehensive yet up-to-date reference on electron transfer processes. Following a foreword by Nobel prize-winner R. A. Marcus, renowned experts from all over the world provide an interdisciplinary overview of every aspect of electron transfer including theoretical-physicochemical backgrounds, latest analytical techniques to identify, monitor and measure the rate of electron transfer, utilizing electron transfer reactions in organic synthesis and catalysis, electron transfer in the gas phase or in special heterogeneous systems such as zeolites or sensitized electrodes. Other central issues are the study of biological systems and the biomimetic electron transfer processes in artificial supramolecular systems. Finally, a complete volume is dedicated to the application of electron transfer in molecular-level electronics, imaging processes and energy conversion. Each chapter is complemented by numerous tables, formulae and illustrations providing an indispensable wealth of information. All references are cross-indexed throughout the work for easy access to this highly complex topic. Whether for quickly looking-up a keyword or as a thorough introduction to a special aspect, this is an essential handbook for everyone working in the field, from experts to postgraduates, from synthetic chemists, physicochemists or biochemists to research groups in material sciences.




Electropharmacology


Book Description

This extraordinary book covers the extremely broad subject of electropharmacology-defined here as the application of principles and methods of electrochemistry to biological topics associated with the action of drugs. It focuses on the physical principles of the movement of electrical charges across interfaces in pharmacological phenomena.
