Alcohol and Aldehyde Metabolizing Systems, Volume III: Intermediary Metabolism and Neurochemistry contains some of the papers presented at the Second International Symposium on Alcohol and Aldehyde Metabolizing Systems, held at the University of Pennsylvania in October 1976. Experts in the field from a wide variety of backgrounds tackled the problems of alcohol and aldehyde metabolism, discussed research findings, and examined controversial issues such as the effects of alcohol and aldehydes on intermediary metabolism. Comprised of 64 chapters, this volume begins with an analysis of the non-equilibrium behavior of biochemical systems, followed by a discussion on the configurational specificity of glycolytic enzymes. The reader is methodically introduced to redox compartmentation and the measurement of intracellular compartmentation of metabolites in rat liver; effect of chronic alcohol and oxygen tension on the development of hepatic necrosis in rats; and actions of ethanol metabolism on fatty acid synthesis in the liver. Subsequent chapters focus on regional metabolic rate in the central nervous system as related to function; effects of tetrahydroisoquinoline derivatives of catecholamines and aldehydes on tyrosine hydroxylase; and lowering of blood acetaldehyde levels as a therapeutic approach to alcoholism. This book will be of value to practitioners and researchers from a variety of disciplines, including neurochemistry, biochemistry, physiology, cell biology, and pharmacology.

Alcohol and Aldehyde Metabolizing Systems, Volume II: Enzymology and Subcellular Organelles contains some of the papers presented at the Second International Symposium on Alcohol and Aldehyde Metabolizing Systems, held at the University of Pennsylvania in October 1976. Experts in the field from a wide variety of backgrounds tackled the problems of alcohol and aldehyde metabolism, discussed research findings, and examined controversial issues ranging from the molecular structure of enzymes to the clinical actions of alcohol in humans. Comprised of 43 chapters, this volume begins by comparing the enzymatically catalyzed oxidation of glyceraldehyde-3-phosphate and lactate, followed by an analysis of liver alcohol dehydrogenase and its mechanism of action. The reader is methodically introduced to the kinetics and mechanism of activated liver alcohol dehydrogenase; structural and functional changes in different alcohol dehydrogenases during evolution; and localization and properties of aldehyde reductase. Subsequent chapters deal with the correlation between the activity of acetaldehyde dehydrogenase and the structure of mitochondria; the distribution of subcellular organelles; and peroxisomes and microsomes. This book will be of value to practitioners and researchers from a variety of disciplines, including biochemistry, physiology, cell biology, and pharmacology.

Control of Energy Metabolism: A Colloquium of the Johnson Research Foundation focuses on the processes, reactions, and approaches involved in the control of energy metabolism. The selection first offers information on the respiratory chain as a model for metabolic control in multi-enzyme systems, dynamics and control in cellular reactions, and computer-based analysis of biochemical data. The text then explores purification and properties of rabbit skeletal muscle phosphofructokinase; multiple forms of heart phosphofructokinase; and mechanisms of inhibition and activation of phosphofructokinase in Novikoff ascites tumor cells. Discussions focus on the properties of purified phosphofructokinase; effect of heart extracts on reactivation of phosphofructokinase; active and inactive forms of phosphofructokinase; and effect of hexose phosphate and adenylic nucleotides on reactivation of phosphofructokinase. The manuscript takes a look at enzyme and metabolite profiles; coordinated stimulation of hexokinase and phosphofructokinase by phosphate in a reconstituted system of glycolysis; control of hexokinase in ascites tumor glycolysis; and cation flux across the mitochondrial membrane as a possible pacemaker of tissue metabolism. The selection is a vital reference for biochemists and researchers interested in the control of energy metabolism.
