Available in PDF, EPUB and Kindle. Book excerpt: "This book is the result of the 2nd International Symposium on Energy and Protein Metabolism and Nutrition. It presents the latest results on energy and protein metabolism and nutrition. It is oriented towards livestock science but also addresses general aspects of protein and energy metabolism as applied to animals or biomedical sciences. The book is based around the following five key topics: * Nutrition and mitochondrial functions * Regulation of body composition and/or product quality by tissue metabolism * ""Omics"" in metabolism and nutrition studies * Coordination between tissues for the metabolic utilisation of nutrients * From the parts to the whole or how to use detailed information to answer applied questions Widely different approaches ranging from fundamental to integrative approaches are applied to key concepts of nutrition. Fundamental research is translated into practical outcomes through active links with applied research and practical applications. The newest research techniques and methods are also addressed and the outcomes presented provide an integrated view of this topic. The conclusions may eventually be integrated into systems of nutritional recommendations as new nutritional challenges emerge. This book will be of interest to all professionals and researchers who concern themselves with developments in animal and human nutrition."

Download or read book Revision and Analyses of Assumptions Used in Describing Energy and Protein Metabolism written by Katherine Marie Kennedy and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of assumptions lies at the base of every experiment and project conducted, regardless if theoretical, mathematical, or experimental. Those assumptions must be as accurate as possible to ensure the accuracy of the project and/or theory. This thesis revises and analyzes the assumptions used in describing energy and protein metabolism, particularly the ATP values associated with the reducing equivalents that are generated through oxidative phosphorylation and the effect those new values of ATP on a variety of energy producing/consuming metabolic pathways in ruminants and non-ruminants. Much of energetics relies on the electron transport chain and ATP synthase, arguably, the most important structures in mammalian cells as a result of its combined capacity for mass production of ATP through oxidation phosphorylation. Over the decades, progress has been made in the determination of the mechanism of each of the five complexes (NADH-ubiquinone oxidoreductase (Complex I), succinate-ubiquinone oxidoreductase (Complex II), cytochrome bc1 complex (Complex III), cytochrome c oxidase (Complex IV), and ATP synthase (Complex V)) and in the determination of the proton pumping stoichiometry associated with complex I, III, and IV. The finding that bovine heart ATP synthase requires the flow of 8 protons from the intermitochondrial membrane space into the mitochondrial matrix through the ATP synthase to produce 3 ATP is one of the most notable of these discoveries. This information, as well as advances in biochemical research, enables the calculation of the values of ATP associated with the reducing equivalents NADH, flavin adenine dinucleotide (FADH2), and guanosine triphosphate (GTP). Those advances include the identification of the costs of: (1) the malate-aspartate shuttle for transporting protons and electrons into the mitochondria, (2) pyruvate transport into the mitochondria, and (3) counter transport of ATP and GTP out of the mitochondria with the concomitant costs of transporting ADP, GDP, and inorganic phosphorous into the mitochondria. As currently accepted, electron transport results in 10 and 6 protons pumped from the matrix to the intermitochondrial space when the electrons are derived from NADH + H+ and FADH2, respectively. Consequently, when each is coupled to oxidative phosphorylation 2.7 ATP are produced from each NADH + H+ formed in the mitochondria, 2.5 ATP from each NADH + H+ formed in the cytosol, and 1.6 ATP from each mitochondrial FADH2. Mitochondrial GTP formed in the TCA cycle is equivalent to 0.7 ATP when GTP is transported out of the mitochondria. These assumptions were then applied to energetics, including the energy associated with AA oxidation. Other key aspects in working with energetics and protein metabolism include establishing values for the following three assumptions: (1) the average molecular weight (MW) of an AA; (2) the percent nitrogen (%N) content of the protein; and (3) the ATP cost associated with the formation of one peptide bond. Assuming that the average MW of an AA is 110 g/mol for a protein is a reasonable assumption when considering the whole organism, but individual tissues may differ. Additionally, although the assumption that livestock muscle products have a %N value of approximately 16% is reasonable, the determination of the %N content based on the AA analysis of the product is best. For decades, the cost of 5 ATP per peptide bond synthesized has been an underlying assumption; however, this research suggests that the cost of synthesizing a peptide bond is 4.1 ATP. Overall, the efficiency of capturing chemical energy as ATP from oxidative processes is decreased when recent research findings are applied to theoretical calculations in both ruminant and non-ruminant animals.

Available in PDF, EPUB and Kindle. Book excerpt: Development in agricultural sciences, particularly in farm animal sciences, resulted in the increased productivity to meet the demand for high quality and relatively cheap protein sources for human nutrition. In parallel, this increased productivity challenges the adequate supply of nutrients, including protein and energy, needed to cover not only high performances, but also insure animal health and welfare, reproduction and quality of products in a sustainable environment. The precise understanding of the animal biology is crucial for animal health and welfare, sustainable animal production, and health of animal product consumers. This book focuses on combining basic and applied research and its practical applications. To achieve these goals, many important topics are presented and discussed in detail. The most important issues in this book are: physiological aspects of protein and energy metabolism and nutrition; animal health and welfare metabolic related issues; effect of feeds and feed processing on energy and protein digestion and metabolism; methodological aspects of research on protein and energy metabolism; environment protection and enhancement of the quality and health-promoting features of animal products. This book constitutes a good source of knowledge for those who like to be up to date with the newest trends and findings in energy and protein metabolism in farm animals.

Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods in Protein Nutrition and Metabolism grew out of a series of seminars (Modern Views in Nutrition) held in 1989 at Iowa State University. These seminars and this book were financed primarily through the Wise and Helen Burroughs Lectureship endowment generously established by the late Dr. Wise Burroughs and his wife Helen. This book comprises 12 chapters, and begins with a focus on amino acid analysis in food and physiological samples. Succeeding chapters go on to discuss concepts and techniques on nitrogen balance; determination of the amino acid requirements of animals; and novel methods for determining protein and amino acid digestibilities in feedstuffs. Other chapters cover measurement of protein digestion in ruminants; evaluation of protein status in humans; surgical models to measure organ amino acid metabolism in vivo; and measurement of whole-body protein content in vivo. The remaining chapters discuss estimation of protein synthesis and proteolysis in vitro; isotopic estimation of protein synthesis and proteolysis in vivo; n-glycine as a tracer to study protein metabolism in vivo; and mathematical models of protein metabolism. This book will be of interest to practitioners in the fields of human nutrition and medicine.

This book was released on 1999-09-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Protein Metabolism and Nutrition written by Seerp Tamminga and published by . This book was released on 1977 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Since protein is so important in the study of nutrition, a symposium was held to examine aspects of protein metabolism in animals, including protein biosynthesis, absorption and turnover. Rates of synthesis and degradation of proteins, as well as the absorption of amino acids from the gastrointestinal tract of ruminants can now be measured. The contents of digested protein and amino acids in feed rations function as indicators for animal protein synthesis; the level of feed intake affects protein production, especially intakes of nitrogen and energy. Digestibilities of amino acids of different feeds containing crude protein are compared. Calculations of nitrogen requirements for cattle have been determined. Protein utilization is influenced by energy losses during urea formation and excretion, and maximal organic digestion depends on ammonia and pH levels. Long term feeding experiments demonstrated the amounts of protein needed for a given production. Production of animal protein in response to human protein demands are discussed.
