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.

This volume is the fourth in the series of the Proceedings of the College Park Colloquia on Chemical Evolution. These Colloquia, and the resulting Proceedings, are presented in the interest of fostering the impact of the interdisciplinary nature of chemical evolu tion on contemporary scientific thought. vii EDITORS'INTRODUCTION The Fourth College Park Colloquium on Chemical Evolution was held on October 18 - 20, 1978 at the University of Maryland. The meeting, supported by the National Aero nautics and Space Administration and the National Science Foundation, centered on the variable environments, both past and present, in which living organisms have survived, grown, and evolved - the limits of life. Previous colloquia had emphasized the Giant Planets (1974) 1, Early Life during the Precambrian (1975)2 and Comparative Planetology (1976)3. The College Park Colloquia have been noted for the broad interdisciplinary nature of the training and interests of the participants. The fourth meeting was no ex ception with the participation of approximately 85 researchers, representing many academic fields. As with previous meetings, the interdisciplinary approach to the question of the limits of life encouraged the exchange of knowledge and information. A major scientific aspiration is to understand why living systems are restricted to certain environments.

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.

This book represents a practical encyclopedia giving information on the unique characteristics and applications of one of the most useful groups of bacteria. This edition differs from those published previously by covering new data obtained by researchers during the last 25 years. Topics covered include: New phylogenetic taxonomy elaborated by modern methods of molecular biology. The peculiarities of the genetic, antimutagenic and reactive properties of propionibacteria in organisms inactivated by different stress factors. The unusual fermentation mechanism, linked with a short chain of electron transport, which generates more energy than the normal modes of fermentation. New functions of vitamin B12 in constructive metabolism, and the ability of B12-deficient cells to switch from an anaerobic to an aerobic style of existence, including the molecular regulation of this metamorphosis. Production of new bacteriocins and new means of propionic acid production, revealing strains producing large quantities of porphyrins, NO and superoxide dismutase. New bacterial combinations for starters in cheese-making and ensilage, increasing the regions of their practical applications. Immunomodulating properties of propionibacteria, and the probiotic characteristics that make them an object of medical and veterinary interest. The book is addressed not only to microbiologists, but also to general biologists, teachers and manufacturers who wish to learn more about the functions of propionic acid bacteria.
