The Alkali Metal Ions: Their Role for Life


Book Description

MILS-16 provides an up-to-date review of the impact of alkali metal ions on life. Their bioinorganic chemistry and analytical determination, the solid state structures of bio-ligand complexes and the properties of alkali metal ions in solution in the context of all kinds of biologically relevant ligands are covered, this includes proteins (enzymes) and nucleic acids (G-quadruplexes). Minerals containing sodium (Na+) and potassium (K+) are abundant in the Earth's crust, making Na+ and K+ easily available. In contrast, the alkali elements lithium (Li+), rubidium, and cesium are rare and the radioactive francium occurs only in traces. Since the intra- and extracellular, as well as the compartmental concentrations of Na+ and K+ differ significantly, homeostasis and active transport of these ions are important; this involves transporters/carriers and pore-forming ion channel proteins. Systems like Na+/K+-ATPases, H+/K+-ATPases or Na+/H+ antiporters are thoroughly discussed. The role of K+ in photosynthesis and the role of Na+ in charging the "battery of life" are pointed out. Also, the relationships between alkali metal ions and diseases (e.g., Parkinson or traumatic brain injury) are covered and the relevance of Li+ salts in medicine (pharmacology and mechanism) is reviewed. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 16, The Alkali Metal Ions: Their Role for Life, which are written by 44 internationally recognized experts from 12 nations. The impact of this vibrant research area is manifested in nearly 3000 references, over 30 tables and more than 150 illustrations (two thirds in color). MILS-16 also provides excellent information for teaching. Astrid Sigel, Helmut Sigel, and Roland K. O. Sigel have long-standing interests in Biological Inorganic Chemistry. Their research focuses on metal ion interactions with nucleotides and nucleic acids and on related topics. They edited previously 44 volumes in the series Metal Ions in Biological Systems.

Metal Ions in Biological Systems


Book Description

This book is wholly devoted to Ca2+ metal ion, as it is so important in regulating a wide variety of biological activities. It deals with calcium and brain proteins, the role of ca2+ in exocytosis, blood coagulation, and the regulation of the skeletal muscle contraction-relaxation cycle.




The Ubiquitous Roles of Cytochrome P450 Proteins


Book Description

Helmut Sigel, Astrid Sigel and Roland K.O. Sigel, in close cooperation with John Wiley & Sons launch a new Series “Metal Ions in Life Sciences”. There exists a whole range of books on Cytochromes P450, but none with the focus of this volume. This new volume in the Series concentrates on current hot topics in the area and tries to work out the underlying common developments. As a result the reader will find a systematic account of new results in this exciting research area. The table of contents gives an idea on the wide span of chapters, starting with overviews and the presentation of specific systems, and ending with chapters on carbon-carbon bond cleavage by P450 sytems, drug metabolism as catalyzed by P450 systems, decomposition of xenobiotics by P450 enzymes and design and engineering of new P450 systems.




Metal Ions in Biology and Medicine


Book Description

Every two years, the world's leading specialists meet to exchange information on the most recent advances in understanding metals and the part they play in treating some diseases, especially cancer. Most of the elements in our environment are metals. Some are essential for life, such as copper, iron, magnesium, manganese, nickel and zinc; others are toxic, such as arsenic, cadmium, lead and mercury. This book aims to help advance our knowledge of the role of metal ions in a number of fields in biology and medicine. It reproduces the papers given at the International Symposium on Metal Ions in Biology and Medicine organised in Munich in May 1998.




The Role of Metal Ions in Biology, Biochemistry and Medicine


Book Description

Metal ions are fundamental elements for the maintenance of the lifespan of plants, animals and humans. Their substantial role in biological systems was recognized a long time ago. They are essential for the maintenance of life and their absence can cause growth disorders, severe malfunction, carcinogenesis or death. They are protagonists as macro- or microelements in several structural and functional roles, participating in many bio-chemical reactions, and arise in several forms. They participate in intra- and intercellular communications, in maintaining electrical charges and osmotic pressure, in photosynthesis and electron transfer processes, in the maintenance of pairing, stacking and the stability of nucleotide bases and also in the regulation of DNA transcription. They contribute to the proper functioning of nerve cells, muscle cells, the brain and the heart, the transport of oxygen and to many other biological processes up to the point that we cannot even imagine a life without metals. In this book, the papers published in the Special Issue “The Role of Metal Ions in Biology, Biochemistry and Medicine” are summarized, providing a picture of metal ion uses in biology, biochemistry and medicine, but also pointing out the toxicity impacts on plants, animals, humans and the environment.




Chemistry


Book Description

Emphasises on contemporary applications and an intuitive problem-solving approach that helps students discover the exciting potential of chemical science. This book incorporates fresh applications from the three major areas of modern research: materials, environmental chemistry, and biological science.




Metal Chelation in Medicine


Book Description

Metal chelators are emerging as versatile tool with many medical applications. Their versatility allows them to be used in chelation therapy for treating diseases caused by toxic and heavy metal poisoning, chelating agents are capable of binding to toxic metal ions to form complex structures which are easily excreted from the body removing them from intracellular or extracellular spaces. In addition, metal chelators can also be applied as contrast agents in MRI scanning. Metal Chelation in Medicine provides a clear and timely perspective on the role of chelating agents in the management of metal intoxications and storage diseases. Written by leaders in the field of chelators, this publication is at the cutting-edge of the subject. It covers a broad range of topics such as the use of metal chelators in non-invasive assessment of brain iron overload, and the treatment of systemic iron overload and neurodegenerative diseases. As such it is particularly valuable to clinicians treating metal poisonings and metal storage diseases. However, it is also a useful text for researchers, industry professionals and university students with a specific interest in medicinal chemistry, chelation, metal ions, imaging and non-invasive techniques.
