Over the last decades, amino acids have been found to be of importance in many fields of science. Apart from their biological function, this family of organic compounds has been employed in the synthesis of a vast variety of salts, with impact on areas such as materials science, pharmaceutical or physical research. This covers a wide range, from the discovery of important ferroelectrics or non-linear optical materials to nutrients, flavor enhancers or drugs. This book describes amino acids and their salts with cations, anions and inorganic compounds from a chemical, physical and crystallographical point of view. Additional data on structural properties, crystal growth and the relation of structure and physical properties of amino acid salts is discussed.

Although introduction of amino acid chelates in mineral nutrition initially met considerable skepticism and controversy, the greater absorption and bioavailability of amino acid chelated minerals compared to nonchelated minerals have been well-documented for decades. Amino Acid Chelation in Human and Animal Nutrition compiles published chemical, nutritional, and clinical studies with new unpublished research. It interprets the combined data for the first time to explain why the body responds to an amino acid chelate differently than it does to inorganic metal salts. Focusing on digestion, the book follows how chelates are absorbed from the stomach and intestines into the mucosal tissue, their movement from the mucosal tissue into the blood, and uptake into tissue and organ cells. Amino Acid Chelation in Human and Animal Nutrition compares amino acid chelate absorption and metabolism and that of inorganic salts of the same minerals. This book mainly focuses on the ingestion of amino acid metal chelates as a way to optimize mineral absorption, but it also provides a fundamental discussion of chelation chemistry. The author includes his own results, as well as alternate interpretations of the results of numerous studies of animal and human amino acid mineral chelate digestion and absorption. The views published in this book are solely the author’s views and do not reflect the views of his company, Albion Laboratories.

Concerns have grown that consumption levels of salt are well above those needed for nutritional purposes and that this can lead to adverse effects on health, in particular cardiovascular disease. Consumers are increasingly looking to reduce their salt intake, making salt reduction a priority for food manufacturers. This is not straightforward, though, as salt plays an important role in food preservation, taste and processability. Written by a team of international experts, Reducing salt in foods provides a unique review of current knowledge in this field. This book is divided into three parts and discusses the major issues concerned with salt reduction and how it may be achieved. Part one reviews the key health issues driving efforts to reduce salt, government action regarding salt reduction and the implications of salt labelling. Consumer perception of salt and views on salt reduction and are also discussed. The second part focuses on the technological, microbiological and sensory functions of salt and strategies that can be taken to reduce salt. The final part of the book outlines strategies which have been taken to reduce salt in particular food groups: meat and poultry, seafood, bread, snack foods, dairy products and canned foods. Reducing salt in foods is an essential reference for health professionals, governments and food manufacturers. Discusses methods to reduce salt while maintaining food sensory quality, shelf-life and processability Provides a unique review of current knowledge in this field An essential reference for health professionals, governments and food manufacturers

This volume is one of those published from the proceedings of the invited lectures to the First International Congress of Comparative Physiology and Biochemistry I organized at Liege (Belgium) in August 1984 under the auspices of the Section of Comparative Physiology and Biochemistry of the International Union of Biological Sciences. In a general foreword to these different volumes, it seems to me appropriate to consider briefly what may be the comparative approach. Living organisms, beyond the diversity of their morphological forms, have evolved a widespread range of basic solutions to cope with the different problems, both organismal and environmental with which they are faced. Soon after the turn of the century, some biologists realized that these solutions can be best comprehended in the frame work of a comparative approach integrating results of physiological and biochemical studies done at the organismic, cellular and molecular levels. The development of this approach amongst both physiologists and biochemists remained, however, extremely slow until recently.

During the past two decades Membrane Science and Technology has made tremendous progress and has changed from a simple laboratory tool to large scale processes with numerous applications in Medicine and Industry. In this volume are collected papers presented at the First Europe Japan Congress on Membrane and Membrane processes, held in Stresa in June 1984. Other contributions to the Conference will be published in a special issue of the Journal of Membrane Science. This Conference was organized by the European Society of Membrane Science and Technology and the Membrane Society of Japan, to bring together European Scientists and Engineers face to face with their colleagues from Japan; in both countries membrane processes will play a strategic role in many industrial areas in the 1990s, as predicted by the Japanese project for Next Generation Industries and by the EEC Project on Basic Techno logical Research (BRITE). The large number of participants, of about four hundred from twenty six countries including USA, Australia, China and Brazil, the quality of the Plenary Lectures and Scientific Communications made the Conference a significant international success.

Amino Acids, Proteins, and Cancer Biochemistry focuses on the contributions of Jesse P. Greenstein to biological chemistry, including kinetics, protein mixtures, metabolism, tumors, and biosynthesis. The selection first offers information on quantitative nutritional and in vivo metabolic studies with water-soluble, chemically defined diets and internal hydrogen bonding in ribonuclease. Discussions focus on the effects of deuterium on transition temperature, kinetics of deuterium-hydrogen exchange, applications of chemically denned diets, formulation of water-soluble, chemically defined diets, and large-scale preparation of optically pure amino acids. The manuscript then examines the chromatographic evaluation of protein mixtures and observations on the activation of amino acids and biosynthesis of peptide bonds, including synthesis of phenylacetylglutamine and benzoylglycine, studies on amino acyl adenylates, and synthesis of glutamine. The publication ponders on free amino acids and related substances in normal and neoplastic tissues; nucleic acids of normal tissues and tumors; and carbohydrate metabolism in ascites tumor and HeLa cells. Topics include carbohydrate metabolism of ascites tumor cells, comparative biochemistry of glycolysis, DNA and the genetic concept of cancer, and constancy of free amino acid patterns of tissues. The selection is a valuable source of data for biochemists and researchers interested in amino acids, proteins, and cancer biochemistry.
