Book Description
The chemical properties of superoxide ion, its biological role, and the role of other oxygen radicals which arise as a result of its transformations are contained in this text. In Volume I the principal reactions of superoxide ion, including protonation reactions with proton donors, nucleophilic reactions with esters, alkyl halides and other compounds, electron transfer reactions with quinones and metal complexes, are described. Basic quantitative data including rate constants and yields for the reactions of superoxide ion of all types are given in tables. This volumecontains the mechanisms of the generation of oxygen radicals in cells and the interaction of superoxide ion with cell components. The role of superoxide ion in lipid peroxidation and destruction of proteins and nucleic acids is explained, as well as oxygen radicals in the mechanisms of toxic and therapeutic action of drugs, especially anticancer antibiotics. In addition, the action of superoxide ion and other oxygen radicals on plants, micro-, and macroorganisms is discussed, along with the role of oxygen radicals in normal metabolic and pathological processes.

Book Description
This book provides a comprehensive treatise on the chemical and biochemical consequences of damaging free radical reactions, the implications for the pathogenesis of disease and how this might be controlled endogenously and by radical scavenging drugs. Oxidative stress may be influenced by exogenous agents of oxidative stress, radiation, trauma, drug activation, oxygen excess, or by exogenous oxidative stress which is associated with many pathological states including chronic inflammatory disorders, cardiovascular disease, injury to the central nervous system, and connective tissue damage. This and many other such aspects are presented clearly and in depth.The development of antioxidant drugs depends on the understanding of the mechanisms underlying the generation of excessive free radicals in vivo, the factors controlling their release and the site of their action. This excellent volume presents an up-to-date account of the current state of knowledge in these areas.

Book Description
This book is written for the research biochemist who needs to know more about the particular field of dioxygen metabolism, whether this be for designing lectures for a graduate level course or for his or her own research needs. We hope researchers in a given area of dioxygen metabolism will gain knowledge of related fields of dioxygen metabolism. We have decided to use the term dioxygen to distinguish molecular oxygen from divalent oxygen in water and organic compounds, dioxygen being a simpler term than molecular oxygen. We do not intend to review the metabolism of all compounds that contain oxygen, since this would include all of biochemistry. An understanding of dioxygen chemistry is essential to the discussion of the biochemistry of dioxygen. While this statement could be made about any biochemical constituent, the chemistry of dioxygen is so unusual that interpre tations without detailed chemical background are futile. Prediction of dioxygen reaction products by analogy with other oxidants is impossible. The partial reduction products of dioxygen, superoxide ion and peroxides, develop naturally in the chemistry of dioxygen. It would be difficult to discuss dioxygen biochemistry without first discussing these partial reduction products.

Book Description
The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.

Book Description
The book is a multi-author survey (in 15 chapters) of the current state of knowledge and recent developments in our understanding of oxide surfaces. The author list includes most of the acknowledged world experts in this field. The material covered includes fundamental theory and experimental studies of the geometrical, vibrational and electronic structure of such surfaces, but with a special emphasis on the chemical properties and associated reactivity. The main focus is on metal oxides but coverage extends from 'simple' rocksalt materials such as MgO through to complex transition metal oxides with different valencies.

Book Description
Examining the formation, transformation, and application of ion radicals in typical conditions of organic synthesis, Organic Ion Radicals: Chemistry and Applications explains the reactions and principles of ion radical chemistry. The author addresses methods of determining ion- radical mechanisms and controlling ion radical reactions, issues relating to ecology and biology, and inorganic participants in ion radical organic reactions. Applications discussed include the roles of ion radicals in biological systems and their uses in optoelectronics, organic metals, and the manufacture of paper.
