The Role of Protein and Amino Acids in Sustaining and Enhancing Performance


Book Description

It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.




Protein Turnover


Book Description

Written by the leading authority in the area, this book provides a comprehensive review of the growing body of research on protein turnover in man and animals that has accumulated over the past 20 years. It focuses on protein metabolism at the physiological level, and particularly with studies on human beings. It discusses the methods that have been used for measuring whole body protein turnover in man, the assumptions underlying this work, and problems that have been encountered.




Nitrogen Metabolism and Excretion


Book Description

Although the basic evolutionary patterns of nitrogen metabolism and excretion have been outlined for decades, there has been a resurgence of research activity in the past 15 years. Research in nitrogen metabolism has been stimulated in the area of acid-base balance. The molecular revolution has had an impact on the field as well, and recent studies on nitrogen metabolism and excretion now almost routinely use the tools of molecular biology. Of special interest are recent studies of evolutionary relationships between proteins of nitrogen metabolism. Nitrogen Metabolism and Excretion updates the reader on progress being made in this subject, offering an exciting integration of traditional topics and discussions on the most recent issues which have not yet appeared in other textbooks or references. The book features chapters on the latest developments in nitrogen metabolism and excretion from 28 prominent researchers from all over the world. Each chapter is detailed and specific, filled with useful concepts and techniques. The scope of the book is broad and diverse, covering groups from invertebrates to mammals, and subjects from nitrogen in oceanic buoyancy regulation to molecular mechanisms of nitric oxide synthesis. The text provides a phylogenetic view of various animal groups and presents much new information intended to break down phylogenetic stereotypes. The general areas of development, maternal-fetal interactions, protein turnover, carbamoyl phosphate synthesis, nitric oxide, and nitrates and nitrites are also covered in depth. This volume is the first in a new series that brings about a modern synthesis of areas of animal physiology. Nitrogen Metabolism and Excretion benefits both established researchers interested in nitrogen and advanced undergraduate and graduate students who want to investigate the most current and exciting questions being studied and debated.




Principles of Exercise Biochemistry


Book Description

This unique volume provides a comprehensive review of the biochemistry of exercise. Written by internationally renowned experts, the publication has been completely revised and updated. The present edition follows the new concepts of applied biochemistry which have emerged recently in the scientific literature. Genomics, proteomics, and metabolomics are nowadays common terms used to the elucidation of gene function, expression of proteins and comprehensive analysis of all the metabolites in a tissue. The major steps of biochemistry are considered in active survey in this new 3rd edition of an already acclaimed publication. The book is a valuable source for all exercise biochemists and physiologists, sports physicians, graduate students in physical education and physical therapy, and postgraduate research fellows.




Mammalian Protein Metabolism


Book Description

Mammalian Protein Metabolism, Volume IV is an 11-chapter text that describes the regulation of protein metabolism in mammals, both at the subcellular level and at the level of the intact organ and of the whole animal. The first two chapters deal with the fundamental control mechanisms in the synthesis and turnover of proteins, followed by chapters on the mode of action of hormones on protein metabolism and on the role of free amino acid pools in regulation. These topics are followed by discussions on the regulation of individual amino acid pathways and the diurnal rhythms in protein metabolism. The final chapters explore the regulation of protein metabolism in four major organs and tissues of the body, including the gastrointestinal tract, liver, kidney, and musculature. This book will be of great benefit to biologists, researchers, and biology students.




Animal Stress


Book Description

Based on a recent symposium that brought together experts in behavior, nutrition, physiology, immunology, and human and animal medicine, this volume presents an up-to-date discussion of the problems and methods of studying animal stress today. Section one reviews the evolutionary and ontogenetic determinants of animal suffering and the assessment of well-being. The second section examines biological responses to stress and methods of monitoring stress in animals. Section three shows how stress can threaten animal health, disrupt normal reproduction, and influence growth and metabolism. The final section relates the importance of animal stress to developing guidelines on the use of animals in scientific research. This is an invaluable reference for exploring these complex responses




Processing and Turnover of Proteins and Organelles in the Cell


Book Description

Processing and Turnover of Proteins and Organelles in the Cell is a collection of papers that tackles the problems of post-translational processes, along with the dynamics of cell components. The materials in the title are organized thematically. The text first presents articles dealing with post-translational processing, such as the mode of anchoring of sucrase-isomaltase to the small intestinal brush-border membrane and its biosynthetic implications, as well as the decay and restoring in succinate dehydrogenase. The next papers discuss topics related to the selective degradation of proteins, such as selective control of proteinase action in yeast cells and studies of the mechanism and selectivity of intracellular protein breakdown. The final set of papers covers the turnover of organelles, which includes biogenesis and turnover of peroxisomes, and the effect of oxygen on the synthesis of mitochondrial proteins in Saccharomyces cerevisiae. The book will be of great use to microbiologists and biochemists. Scientists from biological science disciplines will also benefit from the text.
