Description

Current Topics in Bioenergetics, Volume 5 provides information pertinent to the molecular properties of purified enzymes and defined reactions. This book presents the development in the research on oxidative phosphorylation.

Organized into nine chapters, this volume begins with an overview of the contributions to the knowledge of membrane structure based on X-ray diffraction analysis. This text then examines the reactions of chlorophyll in model systems and the luminescence linked with light absorptions, which relate to the early events in photosynthesis. Other chapters relate spectroscopic and EPR measurements to redox changes linked with energy coupling in the mitochondrial electron carriers. This book discusses as well the role of soluble proteins in the energy transfer process of oxidative phosphorylation. The final chapter deals with the chemical and structural properties of the photoreceptors in the visual process.

This book is a valuable resource for biophysicists, physiologists, biologists, biochemists, physical chemists, and research workers.

Lester Packer

Lester Packer

Lester Packer received a PhD in Microbiology and Biochemistry in 1956 from Yale University. In 1961, he joined the University of California at Berkeley serving as Professor of Cell and Molecular Biology until 2000, and then was appointed Adjunct Professor, Pharmacology and Pharmaceutical Sciences, School of Pharmacy at the University of Southern California.

Dr Packer received numerous distinctions including three honorary doctoral degrees, several distinguished Professor appointments. He was awarded Chevalier de l’Ordre National du Merite (Knight of the French National Order of Merit) and later promoted to the rank of Officier. He served as President of the Society for Free Radical Research International (SFRRI), founder and Honorary President of the Oxygen Club of California.

He has edited numerous books and published research; some of the most cited articles have become classics in the field of free radical biology:

Dr Packer is a member of many professional societies and editorial boards. His research elucidated - the Antioxidant Network concept. Exogenous lipoic acid was discovered to be one of the most potent natural antioxidants and placed as the ultimate reductant or in the pecking order of the “Antioxidant Network” regenerating vitamins C and E and stimulating glutathione synthesis, thereby improving the overall cellular antioxidant defense. The Antioxidant Network is a concept addressing the cell’s redox status. He established a world-wide network of research programs by supporting and co-organizing conferences on free radical research and redox biology in Asia, Europe, and America.
