Biochemistry Of The Lanthanides

By a happy coincidence, the completion of this text coincided with the 200th anniversary of the discovery of gadolinite, the mineral with which the lanthanide story begins. For a group of elements which occur in only trace amounts biologically, and which have no known metabolic role, the lanthanides have spawned a surprisingly large biochemicalliterature. Se rious interest in the biochemical properties ofthese elements can be traced to concerns about the safety of radioactive lanthanides toward the end of World War 11. As recent events at Chernobyl indicate, this concern re mains topical. However, the literature on lanthanide biochemistry pre dates the atomic era, beginning with sporadic, medically motivated studies in the latter part of the 19th century. Much of the present biochemical activity involving the lanthanides centers around their ability to provide 2 important information on the interactions of Ca + with macromolecules and with eukafyotic cells. With the increasing industrial use of the lan thanides, their toxicological properties will need to be examined more closely. Rare earth pneumonoconiosis has already been identified as a disease produced by industrial exposure to lanthanides. Several of the biochemical properties of the lanthanides are of relevance to modern medicine. Already cerium-based ointments are used to treat burn wounds, while paramagnetic lanthanides find application in nuclear magnetic res onance imaging. This book is an attempt to collate and to present in reasonable detail existing knowledge of lanthanide biochemistry before the literature be comes unmanageable.

Lanthanides have fascinated scientists for more than two centuries now, and since efficient separation techniques were established roughly 50 years ago, they have increasingly found their way into industrial exploitation and our everyday lives. Numerous applications are based on their unique luminescent properties, which are highlighted in this volume. It presents established knowledge about the photophysical basics, relevant lanthanide probes or materials, and describes instrumentation-related aspects including chemical and physical sensors. The uses of lanthanides in bioanalysis and medicine are outlined, such as assays for in vitro diagnostics and research. All chapters were compiled by renowned scientists with a broad audience in mind, providing both beginners in the field and advanced researchers with comprehensive information on on the given subject.

The Metal Ions in Biological Systems series is devoted to increasing our understanding of the relationship between the chemistry of metals and life processes. The volumes reflect the interdisciplinary nature of bioinorganic chemistry and coordinate the efforts of researchers in the fields of biochemistry, inorganic chemistry, coordination chemistry, environmental chemistry, biophysics, pharmacy, and medicine. Written by 36 internationally recognized experts and enriched with nearly 200 illustrations, Volume 40 highlights fast moving research on lanthanides and their interrelations with biosystems and emphasizes their recent impact in biochemical and biological studies, and in medicine.

The second edition of Metal Ions in Biochemistry deals with the multidisciplinary subject of bio-inorganic chemistry, encompassing the disciplines of inorganic chemistry, biochemistry and medicine. The book deals with the role of metal ions in biochemistry, emphasising that biochemistry is mainly the chemistry of metal-biochemical complexes. Hence, the book starts with the structures of biochemicals and the identification of their metal binding sites. Thermodynamic and kinetic properties of the complexes are explained from the point of view of the nature of metal-ligand bonds. Various catalytic and structural roles of metal ions in biochemicals are discussed in detail. Features The role of Na+ and K+ in brain chemistry. The role of zinc insulin in glucose metabolism and its enhancement by vanadium and chromium compounds. Discussion of the role of zinc signals, zinc fingers and cascade effect in biochemistry. Haemoglobin synthesis and the role of vitamin B12 in it. The role of lanthanides in biochemical systems. A detailed discussion of the role of non-metals in biochemistry, a topic missing in most of the books on bio-inorganic chemistry. The study of bio-inorganic chemistry makes biochemists rethink the mechanistic pathways of biochemical reactions mediated by metal ions. There is a realisation of the role of metal complexes and inorganic ions as therapeutics such as iron in leukaemia, thalassemia and sickle cell anaemia, iodine in hypothyroidism and zinc, vanadium and chromium in glucose metabolism. The most recent realisation is of the use of zinc in the prevention and treatment of COVID-19.

This book presents an overview of the entire field of cadherin research and provides the current basic concept of cadherins. Cadherins have been widely accepted as key regulators of animal development and physiological functions, and it also has become clear that they play essential roles in various human diseases. With contributions by leading scientists, the book covers various aspects of the cadherin superfamily including the history of cadherin research, basic properties of classical cadherins as well as non-classical cadherins, cadherin-associated proteins, and the roles of cadherins in health and diseases. In addition, the book presents some contradictory results and important unanswered questions, and the authors propose their working hypotheses or future directions, to inspire future studies. This volume enables graduate students and young researchers to learn the basics and gain a comprehensive image of the cadherin superfamily, and experts in the field will easily find various topics of interest in relevant areas of study. Additionally, a list of cadherin-related diseases is included for quick reference to cadherins in human diseases.

This volume of the Handbook is the second of a three-volume set of reviews devoted to the interrelationships, similarities, differences, and contrasts of the lanthanide and actinide series of elements. In particular this book considers the comparisons of the chemistry of the lanthanide and actinide elements. The lanthanide and actinide elements present a multitude of challenging physical and chemical problems resulting from the involvement of open F-shell electronic configurations. This is made clear in the chapters composing these volumes which cover topics such as: the experimental and theoretical aspects of solution absorption and luminescence spectra to reveal similarities and differences in the two f-series; the methods and effectiveness of separation by solvent extraction, ion exchange and necessary accompanying reactions; the comparative thermochemical and oxidation-reduction properties of lanthanide and actinide materials; interrelationships and comparisons of the halides; an examination of the relative hydration and hydrolysis behaviors of the lanthanides and actinides.

Biochemistry of Scandium and Yttrium gathers together existing knowledge about scandium and yttrium from a wide variety of disciplines. Part 1 will present a comparative study of the physical and chemical properties of scandium and yttrium, looking at both their similarities and their differences. (Part 2 will address the biochemical aspects of these two elements, and the various medical and environmental applications.) While these elements are relatively rare in nature, these books will show that they have unusual physical and chemical properties, and a disproportionate number of important applications. Improved analytical techniques have revealed that scandium and yttrium are present throughout living matter, even though only a relatively limited number of species have been analyzed so far. This fact of course has far-ranging implications for biological and environmental concerns. Part 1 also contains a discussion of the interactions of scandium and yttrium with molecules of biological interest, such as organic acids, carbohydrates, proteins, nucleotides, and other biologically active molecules. The major impacts of scandium and yttrium in science, technology, and medicine will be of interest to a wide variety of researchers, including geochemists, inorganic and organic chemists, clinical biochemists, and those specializing in environmental protection. Biochemistry of Scandium and Yttrium, Part 1 and Part 2 will be especially welcome because the last book published on the biochemistry of scandium appeared over 20 years ago, and the only book mentioning the biochemistry of yttrium came out in 1990.
