Available in PDF, EPUB and Kindle. Book excerpt: Function of Quinones in Energy Conserving Systems covers the vast amount of research on the unique function of quinones in electron transfer and energy conserving systems. This book is organized into seven parts encompassing 39 chapters that focus on the quinone-protein interactions. The opening part discusses the progression and status of research on ubiquinone proteins in mitochondria. This topic is followed by discussions on the electrochemical and spectral properties of quinones and semiquinones, as well as on a model for quinone-cytochrome electron-transfer reactions, with an emphasis on the derived kinetic advantages from altering the ubiquinol ionizability. The third part describes the properties and possible function of the quinone pool and the relationship and possible exchange between bulk phase and bound quinone. The subsequent parts look into the possible function of thermodynamically stable semiquinones and quinone binding proteins in mitochondria and photosynthetic systems. These parts also explore the application of inhibitory analogs and photoactivatable derivatives to identify the proteins that may interact directly with quinones. This text further discusses the function of plastoquinone in the photosynthetic reaction centers and the b-f complex. The concluding part examines the pathways of electron transfer in energy transducing membranes, with a particular emphasis on protonmotive mechanisms of quinone function. This book will be of value to biologists, researchers, and biology teachers and students.

Available in PDF, EPUB and Kindle. Book excerpt: The photosynthetic process of higher plants converts carbon dioxide, water, and, light quanta into reduced sugars. The enzymes which catalyze this conversion are contained within the chloroplasts and can be thought of as split into two distinct groups. In one group are the enzymes of the IIlightll reactions, which harvest the light, oxidize water and generate two energy-rich intermediates, ATP and NADPH. These two intermediates plus carbon dioxide are the substrates for the second group, the IIdarkll reactions or Cal vi n cycle, which produce the reduced sugars. The chloroplast is completely bounded by an outer membrane. There is a separate, highly convoluted membrane system, the thyla koid system, enclosed within the chloroplast. The enzymes of the light reactions are physically associated with the thylakoid mem branes, while the Calvin cycle enzymes are free-floating within the stroma, or soluble part of the chloroplast (Fig. 1).

Book excerpt: These four volumes with close to one thousand contributions are the proceedings from the VIIIth International Congress on Photosynthesis, which was held in Stockholm, Sweden, on August 6- 11, 1989. The site for the Congress was the campus of the University of Stockholm. This in itself was an experiment, since the campus never before had been used for a conference of that size. On the whole, it was a very sucessful experiment. The outcome of a congress depends on many contributing factors, one major such factor being the scientific vigour of the participants, and I think it is safe to say that the pariticipants were vigourous indeed. Many exciting new fmdings were presented and thoroughly dicussed, indoors in the discussion sessions as well as outdoors on the lawns. For the local organizing committee it was very rewarding to participate in these activities, and to watch some of our younger colleagues for the first time being subjected to the impact of a large international congress. The stimulating effect of this event on the local research atmosphere has been substantial. As was the case with the proceedings from both the 1983 and 1986 Congresses these proceedings have been compiled from camera ready manuscripts, and the editing has mainly consisted of finding the proper place for each contribution and distributing the manuscripts into four volumes with some int~rnal logic in each. In this I have had the invaluable help from Dr.

Book excerpt: There has been an explosion of research related to free radicals and antioxidants in recent years, and hundreds of laboratories worldwide are actively involved in many as pects of free radicals, oxidative stress, and antioxidants. The literature on these topics in creases exponentially every year. Over the last few years, we have been fortunate to witness a widespread recognition of the important role of free radicals in a wide variety of pathological conditions including diseases such as atherosclerosis, cardiovascular and neurological diseases, ischemia, emphysema, diabetes, radiation injury, cancer, etc. In ad dition, many laboratories are studying the role of free radicals in the inexorable process of aging. Increased evidence involves free radicals with the etiology of various diseases, thereby suggesting the use of antioxidants as a viable therapeutic approach for the treat ment of free radical mediated pathologies. Despite these impressive developments, many important aspects of free radical and antioxidant research are open for investigation. It is important to understand the overall mechanisms involved in free radical mediated physiological and pathological conditions. This knowledge will undoubtedly lead to the development of new therapeutic approaches to prevent or control free radical related diseases. This book contains the proceedings of the NATO Advanced Study Institute (ASI) on "Free Radicals, Oxidative Stress, and Antioxidants: Pathological and Physiological Sig nificance," which was held in Antalya, Turkey from May 24-June 4, 1997.

This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of the science of photobiology can be divided into four cate gories: to develop (1) ways to optimize the beneficial effects of light on man and his environment, (2) methods to protect organisms, including man, from the detrimental effects of light, (3) photochemical tools for use in studies of life processes, and (4) photochemical therapies in medicine. To achieve these goals will require the knowledgeable collaboration of biologists, chemists, engineers, mathematicians, physicians, and phys icists, because photobiology is a truly multidisciplinary science. While a multidisciplinary science is more intellectually demanding, it also has a greater potential for unexpected breakthroughs that can occur when data from several areas of science are integrated into new concepts for the oretical or practical use. Photochemical and Photobiological Reviews continues to provide in-depth coverage of the many specialty areas of photobiology. It is hoped that these reviews will provide an important service to the younger sci entists in the field and to senior scientists in related fields, because they provide a ready access to the recent literature in the field, and more importantly, they frequently offer a critical evaluation of the direction that the field is taking, or suggest a redirection when appropriate.

Available in PDF, EPUB and Kindle. Book excerpt: "Life Is Bottled Sunshine" [Wynwood Reade, Martyrdom of Man, 1924]. This inspired phrase is a four-word summary of the significance of photosynthesis for life on earth. The study of photosynthesis has attracted the attention of a legion of biologists, biochemists, chemists and physicists for over 200 years. Discoveries in Photosynthesis presents a sweeping overview of the history of photosynthesis investigations, and detailed accounts of research progress in all aspects of the most complex bioenergetic process in living organisms. Conceived of as a way of summarizing the history of research advances in photosynthesis as of millennium 2000, the book evolved into a majestic and encyclopedic saga involving all of the basic sciences. The book contains 111 papers, authored by 132 scientists from 19 countries. It includes overviews; timelines; tributes; minireviews on excitation energy transfer, reaction centers, oxygen evolution, light-harvesting and pigment-protein complexes, electron transport and ATP synthesis, techniques and applications, biogenesis and membrane architecture, reductive and assimilatory processes, transport, regulation and adaptation, Genetics, and Evolution; laboratories and national perspectives; and retrospectives that end in a list of photosynthesis symposia, books and conferences. Informal and formal photographs of scientists make it a wonderful book to have. This book is meant not only for the researchers and graduate students, but also for advanced undergraduates in Plant Biology, Microbiology, Cell Biology, Biochemistry, Biophysics and History of Science.

Available in PDF, EPUB and Kindle. Book excerpt: Chlorophyll a Fluorescence: A Signature of Photosynthesis highlights chlorophyll (Chl) a fluorescence as a convenient, non-invasive, highly sensitive, rapid and quantitative probe of oxygenic photosynthesis. Thirty-one chapters, authored by 58 international experts, provide a solid foundation of the basic theory, as well as of the application of the rich information contained in the Chl a fluorescence signal as it relates to photosynthesis and plant productivity. Although the primary photochemical reactions of photosynthesis are highly efficient, a small fraction of absorbed photons escapes as Chl fluorescence, and this fraction varies with metabolic state, providing a basis for monitoring quantitatively various processes of photosynthesis. The book explains the mechanisms with which plants defend themselves against environmental stresses (excessive light, extreme temperatures, drought, hyper-osmolarity, heavy metals and UV). It also includes discussion on fluorescence imaging of leaves and cells and the remote sensing of Chl fluorescence from terrestrial, airborne, and satellite bases. The book is intended for use by graduate students, beginning researchers and advanced undergraduates in the areas of integrative plant biology, cellular and molecular biology, plant biology, biochemistry, biophysics, plant physiology, global ecology and agriculture.

Book excerpt: This volume contains the contributions from the speakers at the NATO Advanced Research Workshop on "Structure of the Photosynthetic Bacterial Reaction Center X-ray Crystallography and Optical Spectroscopy with Polarized Light" which was held at the "Maison d'Hotes" of the Centre d'Etudes Nucleaires de Cadarache in the South of France, 20-25 September, 1987. This meeting continued in the spirit of a previous workshop which took place in Feldafing (FRG), March 1985. Photosynthetic reaction centers are intrinsic membrane proteins which, by performing a photoinduced transmembrane charge separation, are responsible for the conversion and storage of solar energy. Since the pioneering work of Reed and Clayton (1968) on the isolation of the reaction center from photosynthetic bacteria, optical spectroscopy with polarized light has been one of the main tools used to investigate the geometrical arrangement of the various chromophores in these systems. The recent elucidation by X-ray crystallography of the structure of several bacterial reaction centers, a breakthrough initiated by Michel and Deisenhofer, has provided us with the atomic coordinates of the pigments and some details about their interactions with neighboring aminoacid residues. This essential step has given a large impetus both to experimentalists and to theoreticians who are now attempting to relate the X-ray structural model to the optical properties of the reaction center and ultimately to its primary biological function.
