Progress in Research on Energy and Protein Metabolism available in PDF, EPUB and Kindle. "This book compiles the scientific content of the International Symposium on Energy & Protein Metabolism and Nutrition, in Rostock-Warnemünde 13th-18th September 2003. Specialists from all over the world working in energy and protein metabolism research were assembled to discuss scientific matters of physiology, nutrition, immunology and genetics. All scientific contributions, presented as oral communications or posters, are published in this book. Additionally to these more than 150 articles and 10 review papers, presented by invited speakers, give an overview of the state of the art in special research areas of energy and protein metabolism. The book presents latest results in topics of energy metabolism such as environmental aspects of energy homeostasis, dietary and genetic aspects as well as tissue, organ and whole body energy metabolism and methodology. Furthermore this compilation also gives insight in current affairs of protein research, i.e. protein metabolism and microbiology in the gastro-intestinal tract and requirements and post-absorptive metabolism of amino acids. Apart from these specific questions other topics concerning genes and nutrition or modelling and regulation of energy and protein status were of common interest. The intention of these proceedings is to disseminate latest perceptions of energy and protein research and with this to attempt the connection of areas in animal and human life sciences."

Energy and protein metabolism and nutrition available in PDF, EPUB and Kindle. "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."

Revision and Analyses of Assumptions Used in Describing Energy and Protein Metabolism available in PDF, EPUB and Kindle. 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.

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.
