Download The Nutritional Biochemistry of Chromium(III) in PDF, Epub, and Kindle

Chromium nutritional supplements are the second best selling mineral supplements after calcium as chromium is found in pills, sports drinks, chewing gums, smoothies, and numerous other products. Chromium has been promoted to promote weight loss and muscle development and most recently to be available to treat the symptoms of type 2 diabetes and related conditions. The aim of The Nutritional Biochemistry of Chromium(III) is to examine the four most controversial areas of chromium nutrition and biochemistry: - is chromium an essential element for humans and are chromium nutritional supplements of value? - what biochemical role, if any, does chromium play in the body - can large doses of chromium(III) be used to treat symptoms of type 2 diabetes, cardiovascular disease, and related medical conditions - is the use of chromium(III) supplements a health concern. Scientific experts, who are recognized leaders in the field, weigh in with their opinions on both sides of these issues in this book. A background review of the field from 1955-1995 by Vincent opens the book and concludes with a summary by Dr. Forrest Nielsen, Center Director of the USDA's Grand Forks Human Nutrition Research Center concludes the book. * Point-counterpoint format, providing both sides of major issues * Complete coverage of current issues, including nutrition, health, biochemical role and toxicology * Authors are recognised experts and leaders in this field

Download High Resolution EPR in PDF, Epub, and Kindle

Metalloproteins comprise approximately 30% of all known proteins, and are involved in a variety of biologically important processes, including oxygen transport, biosynthesis, electron transfer, biodegradation, drug metabolism, proteolysis, and hydrolysis of amides and esters, environmental sulfur and nitrogen cycles, and disease mechanisms. EPR spectroscopy has an important role in not only the geometric structural characterization of the redox cofactors in metalloproteins but also their electronic structure, as this is crucial for their reactivity. The advent of x-ray crystallographic snapshots of the active site redox cofactors in metalloenzymes in conjunction with high-resolution EPR spectroscopy has provided detailed structural insights into their catalytic mechanisms. This volume was conceived in 2005 at the Rocky Mountain Conference on Analytical Chemistry (EPR Symposium) to highlight the importance of high-resolution EPR spectroscopy to the structural (geometric and electronic) characterization of redox active cofactors in metalloproteins. We have been fortunate to have enlisted internationally recognized experts in this joint venture to provide the scientific community with an overview of high-resolution EPR and its application to metals in biology. This volume, High-Resolution EPR: Applications to Metalloenzymes and Metals in Medicine, covers high-resolution EPR methods, iron proteins, nickel and copper enzymes, and metals in medicine. An eloquent synopsis of each chapter is provided by John Pilbrow in the Introduction. A second volume, Metals in Biology: Applications of High-Resolution EPR to Metalloenzymes, will appear later this year covering the complement of other metalloproteins. One of the pioneers in the development of pulsed EPR and its application to metalloproteins was Arthur Schweiger, whose contribution we include in this volume. Unfortunately, he passed away suddenly during the preparation of this volume. The editors and coauthors are extremely honored to dedicate this volume to the memory of Arthur Schweiger in recognition of his technical advances and insights into pulsed EPR and its application to metalloproteins. Arthur was extremely humble and treated everyone with equal respect. He was a gifted educator with an ability to explain complex phenomena in terms of simple intuitive pictures, had a delightful personality, and continues to be sadly missed by the community. It is an honor for the editors to facilitate the dissemination of these excellent contributions to the scientific community. Suggestions for future volumes are always appreciated.

Download Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc in PDF, Epub, and Kindle

This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Download The Nutritional Trace Metals in PDF, Epub, and Kindle

The Nutritional Trace Metals covers the roles played by trace metals in human metabolism, a relatively neglected area of human metabolism and nutrition. The book focuses its attention on the vital roles played by the relatively small number of trace metal nutrients as components of a wide range of functional proteins. Its structure and content are largely based on the approach adopted by the author, Professor Conor Reilly, during more than 30 years of teaching nutrition to a wide range of undergraduate and postgraduate students. The introductory chapter covers the roles of metals in life processes, the metal content of living systems and metals in food and diets. This is followed by chapters, each dealing with an individual trace metal. Those discussed are iron, zinc, copper, selenium, chromium, manganese, molybdenum, nickel, boron, vanadium, cobalt, silicon and arsenic. In each case attention is given to the metal's chemistry and metabolic roles, including absorption, transport, losses, status and essentiality, as well as the consequences both of deficiency and excess. The Nutritional Trace Metals is essential reading for nutritionists, dietitians and other health professionals, including physicians, who wish to know more about these vital components of the diet. The book will also be of value to food scientists, especially those involved in food fortification and pharmaceutical product formulation. It will be an invaluable reference volume in libraries of universities and research establishments involved in nutrition teaching and research. Conor Reilly is Emeritus Professor of Public Health at the Queensland University of Technology, Brisbane, Australia, and is also Visiting Professor of Nutrition at Oxford Brookes University, Oxford, U.K.

Download The Bioinorganic Chemistry of Chromium in PDF, Epub, and Kindle

Chromium exists in nature as complexes of two stable oxidation states – trivalent chromium(III) and hexavalent chromium(VI). Although trivalent chromium is required in trace amounts for sugar and lipid metabolism in humans and its deficiency may cause a disease called chromium deficiency; hexavalent chromium is toxic and carcinogenic. As chromium compounds were used in dyes and paints and the tanning of leather, these compounds are often found in soil and groundwater at abandoned industrial sites, now needing environmental cleanup and remediation. The Bioinorganic Chemistry of Chromium: From Biochemistry to Environmental Toxicology takes a critical look at what the biochemical data indicate about chromium's role in the body and the biological mechanisms of its toxicology. Topics covered include: What do we know about the biochemical roles and mechanisms of chromium? Is chromium an essential element in the mammalian diet? Is chromium(III) effective as a nutraceutical, a therapeutic agent, and as a supplement in animal feed? What is the biochemistry behind the toxicology of chromium(III) and chromium(VI):the mechanisms of metabolism, genetic and epigenetic effects, and disruption of cell signalling? What are the current chromium(VI) policies and positions from regulatory agencies? The Bioinorganic Chemistry of Chromium: From Biochemistry to Environmental Toxicology is an important contribution to the bioinorganic and trace element biochemical fields which will find a place on the bookshelves of bioinorganic chemists, biochemists, inorganic chemists, toxicologists, nutritionists and regulatory affairs professionals.

Download Cellular Effects of Heavy Metals in PDF, Epub, and Kindle

The term “heavy metals” is used as a group name of toxic metals and metalloids (semimetals) causing contaminations and ecotoxicity. In strict chemical sense the density of heavy metals is higher than 5 g/cm3. From biological point of view as microelements they can be divided into two major groups. a. For their physiological function organisms and cells require essential microelements such as iron, chromium (III), cobalt, copper, manganese, molidenium, zinc. b. The other group of heavy metals is toxic to the health or environment. Of highest concern are the emissions of As, Cd, Co, Cu, Hg, Mn, Ni, Pb, Sn, Tl. The toxicity of heavy metals is well known at organizational level, while less attention has been paid to their cellular effects. This book describes the toxicity of heavy metals on microorganisms, yeast, plant and animal cells. Other chapters of the book deal with their genotoxic, mutagenic and carcinogenic effects. The toxicity of several metals touch upon the aspects of environmental hazard, ecosystems and human health. Among the cellular responses of heavy metals irregularities in cellular mechanisms such as gene expression, protein folding, stress signaling pathways are among the most important ones. The final chapters deal with biosensors and removal of heavy metals. As everybody is eating, drinking and exposed to heavy metals on a daily basis, the spirit of the book will attract a wide audience.
