Download or read book Oxygen Chemistry written by Donald T. Sawyer and published by Oxford University Press. This book was released on 1991-09-19 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book places oxygen on the center stage of chemistry in a manner that parallels the focus on carbon by 19th century chemists. One measure of the significance of oxygen chemistry is the greater diversity of oxygen-containing molecules than of carbon-containing molecules. One of the most important compounds is water, containing the properties of being a unique medium for biological chemistry and life, the source of all the dioxygen in the atmosphere, and the moderator of the earth's climate. Sawyer first introduces the biological origins of dioxygen and role of dioxygen in aerobic biology and oxidative metabolism, and in separate chapters discusses the oxidation-reduction thermodynamics of oxygen species, and the nature of the bonding for oxygen in its compounds. Additional chapters focus on the reactivities of specific oxygen compounds. The book will be of interest to chemists and biochemists, as well as graduate students, life scientists, and medical researchers.

Download or read book Regulation of Tissue Oxygenation Second Edition written by Roland N. Pittman and published by Biota Publishing. This book was released on 2016-08-18 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Download or read book Active Oxygen in Biochemistry written by Valentine Angelou and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of "Oxygen Activation" has attracted considerable interest recently, not only because it presents challenges in those fields of basic research that aim to understand the fundamental aspects of chemical and biological reactions that involve dioxygen, but also because of its wide range of practical implications in such diverse fields as medicine, synthesis of pharmaceuticals and other organic compounds, materials science, and atmospheric science. This is the second of two volumes that focus on the subject of oxygen activation, the first slanted toward chemistry and the second toward biological chemistry. We planned these volumes to be more general than many monographs of this sort, not as detailed summaries of the authors' own research but rather as general overviews of the field. Our choice of topics was strongly influenced by our syllabus for a course entitled "Oxygen Chemistry," which two of us have twice taught jointly at UCLA. Definition of important issues, horizons, and future prospects was an important goal, and, although totally comprehensive coverage was not possible, we believe that we have chosen a representative selection of research topics current to the field. We have targeted this work to a diverse audience ranging from professionals in fields from physics to medicine to beginning graduate students who are interested in rapidly acquiring the basics of this field.
Download or read book Chemistry and Biochemistry of Oxygen Therapeutics written by Andrea Mozzarelli and published by John Wiley & Sons. This book was released on 2011-09-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human blood performs many important functions including defence against disease and transport of biomolecules, but perhaps the most important is to carry oxygen – the fundamental biochemical fuel - and other blood gases around the cardiovascular system. Traditional therapies for the impairment of this function, or the rapid replacement of lost blood, have centred around blood transfusions. However scientists are developing chemicals (oxygen therapeutics, or “blood substitutes”) which have the same oxygen-carrying capability as blood and can be used as replacements for blood transfusion or to treat diseases where oxygen transport is impaired. Chemistry and Biochemistry of Oxygen Therapeutics: From Transfusion to Artificial Blood links the underlying biochemical principles of the field with chemical and biotechnological innovations and pre-clinical development. The first part of the book deals with the chemistry, biochemistry, physiology and toxicity of oxygen, including chapters on hemoglobin reactivity and regulation; the major cellular and physiological control mechanisms of blood flow and oxygen delivery; hemoglobin and myoglobin; nitric oxide and oxygen; and the role of reactive oxygen and nitrogen species in ischemia/reperfusion Injury. The book then discusses medical needs for oxygen supply, including acute traumatic hemorrhage and anemia; diagnosis and treatment of haemorrhages in "non-surgical" patients; management of perioperative bleeding; oxygenation in the preterm neonate; ischemia normobaric and hyperbaric oxygen therapy for ischemic stroke and other neurological conditions; and transfusion therapy in β thalassemia and sickle cell disease Finally “old”and new strategies for oxygen supply are described. These include the political, administrative and logistic issues surrounding transfusion; conscientious objection in patient blood management; causes and consequences of red cell incompatibility; biochemistry of red blood cell storage; proteomic investigations on stored red blood cells; red blood cells from stem cells; the universal red blood cell; allosteric effectors of hemoglobin; hemoglobin-based oxygen carriers; oxygen delivery by natural and artificial oxygen carriers; cross-linked and polymerized hemoglobins as potential blood substitutes; design of novel pegylated hemoglobins as oxygen carrying plasma expanders; hb octamers by introduction of surface cysteines; hemoglobin-vesicles as a cellular type hemoglobin-based oxygen carrier; animal models and oxidative biomarkers to evaluate pre-clinical safety of extracellular hemoglobins; and academia – industry collaboration in blood substitute development. Chemistry and Biochemistry of Oxygen Therapeutics: From Transfusion to Artificial Blood is an essential reference for clinicians, haematologists, medicinal chemists, biochemists, molecular biologists, biotechnologists and blood substitute researchers.
Download or read book Oxygen The Key to Stereoelectronic Control in Chemistry written by Igor Alabugin and published by American Chemical Society. This book was released on 2023-05-25 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although carbon is considered the central element of organic chemistry, the broader chemical world has one more star player—oxygen. Billions of years of evolution have filled your room with oxygen as countless cyanobacteria and plants work on changing our planet. Oxygen is everywhere—from geology to biology, from the Earth's crust to the ozone layer. This digital primer aims to analyze chemical reactivity through the prism of oxygen chemistry. The key to understanding this chemistry is the lone pairs of oxygen (i.e., the underutilized "idle" electrons that do not directly contribute to the Lewis structure of molecules). By highlighting the many roles of oxygen, we will illustrate how chemistry rises above the limitations of Lewis structures and how electrons stay neither idle nor "lone" even if they are in "lone pairs" when an oxygen atom is near a reaction center. This digital primer will introduce important types of chemical bonding that transcend undergraduate textbooks but that are likely to drive the development of new chemical reactions in the future.

Download or read book Oxygen written by Nick Lane and published by Oxford University Press, USA. This book was released on 2002 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen offers fresh perspectives on our own lives and deaths, explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas, following chains of evidence, the book ranges through many disciplines, from environmental sciences to molecular medicine. Damage to DNA caused by oxidative stress appears to explain aging and many of its diseases, hence the popularity in alternative health circles of antioxidants. But antioxidants alone fail to prevent aging. Lane suggests two different avenues of study: modulation of the immune system, which generates free radicals as part of its defense against infectious diseases; and ways of improving the health of our cellular mitochondria, on which many age-related ailments seem to depend. Provocative and complexly argued. Copyright ©Kirkus Reviews, used with permission.
