Interest in carnitine and its potential health benefits has surged over the last decade. Carnitine serves a number of biological roles, such as stimulating the oxidation of fat and preventing the accumulation of lactic acid. It is also used as a supplement for weight loss and performance enhancement. This book discusses the functions carnitine fulfills in human biology, with specific emphasis on its roles in skeletal muscle metabolism. It covers carnitine homeostasis and transport, the renal handling of carnitine, and applications of carnitine in human nutrition.

The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.

A little-known protein building block, L-carnitine, is an important ingredient in overall good health. It helps burn carbohydrates and fat, helps control the level of brain transmitters, and helps stave off the destruction caused by free radicals. This supernutrient can play an important role in improving sports performance, maintaining body weight balance, and supports immune function and heart health

The third edition of this leading textbook builds upon the excellent foundation of the previous two editions. It explains and explores the science underlying our current understanding of the interactions between diet and health, and the basis for current dietary goals and recommendations. It also provides a concise and authoritative description of the biochemistry that is essential to an understanding of the functions of nutrients and the importance of diet and nutrition for health and disease. The discussion of metabolic pathways and their regulation is illustrated by clear and simple diagrams, and is linked throughout to nutritional and physiological aspects.

Abstract: The proceedings of a 1985 international symposium for food scientists, clinicians, and nutritionists reviews the current status of research in the carnitine field and the current status of medical care of patients who may benefit from treatment with exogenous carnitine. The text includes 15 detailed reviews grouped among 5 major areas, with numerous abstracts of poster presentations appended to each of these 5 areas. The 5 areas include: carnitine metabolism and function in normal subjects; assay methods for carnitine, carnitine-biosynthetic enzymes, and enzymes that utilize carnitine as a substrate; human carnitine deficiency; deficiencies of enzymes that use carnitine as a substrate; and situations in which carnitine deficiency is secondary to chronic disease states. The use of carnitine supplementation also is discussed. Five workshop summaries concerning the analysis, deficiency diagnosis, and supplementation of carnitine are appended.

Carnitine Biosynthesis, Metabolism, and Functions contains the proceedings of the Virginia Lazenby O'Hara Biochemistry Symposium held in Dallas, Texas, from March 31 to April 1, 1979. The papers explore all aspects of carnitine metabolism, including its biosynthesis, regulation, transport, and functions. Comprised of 24 chapters divided into four sections, this book opens with a brief review of the situation which led to the discovery of carnitine as a vitamin and its role in acetylation. The discussion then turns to the chemistry and biosynthesis of carnitine in Neurospora crassa, rat kidney, and humans. The purification of enzymes involved in the conversion of trimethyllysine to trimethylaminobutyrate is also considered. The following chapters examine carnitine transport across the plasma membrane; formation and utilization of isobutyrylcarnitine; regulation of blood carnitine and carnitine acyltransferases in the perinatal period; and inhibitors of carnitine transport and metabolism. The final section is devoted to medical and clinical aspects of carnitine, touching on topics such as the possible causes and effects of carnitine deficiency in humans; carnitine deficiency in cirrhosis; protective effects of L-carnitine on ischemic heart; and changes in carnitine-linked metabolism during ischemia, thermal injury, and shock. This monograph will be a useful resource for biochemists and those interested in the physiological roles of carnitine.

Nutrient Metabolism, Second Edition, provides a comprehensive overview of the supply and use of nutrients in the human body and how the body regulates intake. Chapters detail the principles determining digestion and absorption of food ingredients and how these compounds and their metabolites get into the brain, cross the placenta and pass through the kidneys. Each nutrient’s coverage contains a nutritional summary that describes its function, its food sources, dietary requirements, potential health risks if deficient, and impact of excessive intake. This handbook contains the latest information on the scope of structures, processes, genes and cofactors involved in maintaining a healthy balance of nutrient supplies. Of interest to a wide range of professionals because nutrient issues connect to so many audiences, the book contains a useful link to dietary supplements. Latest research findings on health and clinical effects of nutrients and of interventions affecting nutrient supply or metabolism Each nutrient covered contains a nutritional summary describing its function, food sources, dietary requirements, potential health risks if deficient, and impact of excessive intake. Nutrient information immediately accessible--from source to effect--in one volume

Nutrient Metabolism defines the molecular fate of nutrients and other dietary compounds in humans, as well as outlining the molecular basis of processes supporting nutrition, such as chemical sensing and appetite control. It focuses on the presentation of nutritional biochemistry; and the reader is given a clear and specific perspective on the events that control utilization of dietary compounds. Slightly over 100 self-contained chapters cover all essential and important nutrients as well as many other dietary compounds with relevance for human health. An essential read for healthcare professionals and researchers in all areas of health and nutrition who want to access the wealth of nutrition knowledge available today in one single source. Key Features * Highly illustrated with relevant chemical structures and metabolic pathways * Foreword by Steven Zeisel, Editor-in-chief of the Journal of Nutritional Biochemistry * First comprehensive work on the subject
