Download or read book Impact of Lipid Peroxidation on the Physiology and Pathophysiology of Cell Membranes written by Angel Catalá and published by Frontiers Media SA. This book was released on 2017-01-17 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general process of lipid peroxidation consists of three stages: initiation, propagation, and termination. The initiation phase of lipid peroxidation includes hydrogen atom abstraction. Several species can abstract the first hydrogen atom and include the radicals: hydroxyl, alkoxyl, peroxyl, and possibly HO* 2. The membrane lipids, mainly phospholipids, containing polyunsaturated fatty acids are predominantly susceptible to peroxidation because abstraction from a methylene group of a hydrogen atom, which contains only one electron, leaves at the back an unpaired electron on the carbon. The initial reaction of *OH with polyunsaturated fatty acids produces a lipid radical (L*), which in turn reacts with molecular oxygen to form a lipid hydroperoxide (LOOH). Further, the LOOH formed can suffer reductive cleavage by reduced metals, such as Fe++, producing lipid alkoxyl radical (LO*). Peroxidation of lipids can disturb the assembly of the membrane, causing changes in fluidity and permeability, alterations of ion transport and inhibition of metabolic processes. In addition, LOOH can break down, frequently in the presence of reduced metals or ascorbate, to reactive aldehyde products, including malondialdehyde (MDA), 4-hydroxy-2-nonenal (HNE), 4-hydroxy-2-hexenal (4-HHE) and acrolein. Lipid peroxidation is one of the major outcomes of free radical-mediated injury to tissue mainly because it can greatly alter the physicochemical properties of membrane lipid bilayers, resulting in severe cellular dysfunction. In addition, a variety of lipid by-products are produced as a consequence of lipid peroxidation, some of which can exert beneficial biological effects under normal physiological conditions. Intensive research performed over the last decades have also revealed that by-products of lipid peroxidation are also involved in cellular signalling and transduction pathways under physiological conditions, and regulate a variety of cellular functions, including normal aging. In the present collection of articles, both aspects (adverse and benefitial) of lipid peroxidation are illustrated in different biological paradigms. We expect this eBook may encourage readers to expand the current knowledge on the complexity of physiological and pathophysiological roles of lipid peroxidation.

Download or read book Diabetes written by Victor R Preedy and published by Academic Press. This book was released on 2020-04-24 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diabetes: Oxidative Stress and Dietary Antioxidants, Second Edition, builds on the success of the first edition, covering updated research on the science of oxidative stress in diabetes and the potentially therapeutic usage of natural antioxidants in the diet and food matrix. The processes within the science of oxidative stress are not described in isolation, but rather in concert with other processes, such as apoptosis, cell signaling and receptor mediated responses. This approach recognizes that diseases are often multifactorial and oxidative stress is a single component of this. Since the publication of the first edition, the science of oxidative stress and free radical biology continues to rapidly advance with thousands of the research articles on the topic. New sections in this update cover the role of dietary advanced glycation end products (AGEs) in causing OS in diabetes, oxidative stress and diabetes-induced bone metabolism, and oxidative stress and diabetic foot ulcer. Saves clinicians and researchers time in quickly accessing the very latest details on a broad range of diabetes and oxidation issues Combines the science of oxidative stress and the putative therapeutic usage of natural antioxidants in the diet, its food matrix or plant Includes preclinical, clinical and population studies to help endocrinologists, diabetologists, nutritionists, dieticians and clinicians map out key areas for research and further clinical recommendations
Download or read book Seafoods Chemistry Processing Technology and Quality written by Fereidoon Shahidi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seafoods are important sources of nutrients for humans. Proteins and non protein nitrogenous compounds play an important role in the nutritional value and sensory quality of seafoods. Consumption of fish and marine oils is also actively encouraged for the prevention and treatment of cardio vascular diseases and rheumatoid arthritis. Highly unsaturated long-chain omega-3 fatty acids are regarded as the active components of marine oils and seafood lipids. The basic chemical and biochemical properties of seafood proteins and lipids, in addition to flavour-active components, their microbiological safety and freshness quality, are important factors to be considered. A presentation of the state-of-the-art research results on seafoods with respect to their chemistry, processing technology and quality in one volume was made possible by cooperative efforts ofan international group of experts. Following a brief overview, the book is divided into three sections. In Part 1 (chapters 2 to 8) the chemistry of seafood components such as proteins, lipids, flavorants (together with their properties and nutritional significance) is discussed. Part 2 (chapters 9 to 13) describes the quality of seafoods with respect to their freshness, preservation, micro biological safety and sensory attributes. The final section of the book (chapters 14 to 16) summarizes further processing of raw material, underutilized species and processing discards for production of value added products.

This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the ARW NATO Conference on "Action of Free Radicals and Active Forms of Oxygen on Lipoproteins and Membrane Lipids: Cellular Interactions and Atherogenesis", held in Bendor, France, October 5-8,1988. Since the pioneer work of Mc Cord and Fridovitch, growing interest has been focused on the study of the role of oxyradicals role in pathology. This interest is reflected in the exponential increase in the number of papers on free radicals, the success of specialized journals and books on this theme, and the organization of national and international meetings. These meetings have discussed, from.a broad point of view, the problems concerning the mechanisms of production of free radicals, their effects on cell CO!1$tituants (lipids, proteins, nucleic acids) and cell function, the methods of analysis of these phenomena, the pathological states in which free radicals may be involved, natural biological defense systems, and the design of "antiradical" therapies. But it is now well established that the most common target of oxy free radicals are membrane lipids because of their chemical nature (cholesterol in saturation, malonic linkage of polyunsaturated fatty acids (PUFA» and of their regular structural arrangement (monolayers in lipoproteins, bilayers in cell membranes). Thus the analysis of the products resulting from the action of oxy free radicals on PUFA is considered the best tool to indirectly evaluate the effects of tissue peroxidations, although the analytical basis for doing so is very questionable.

Download or read book Plant Lipid Metabolism written by J.C. Kader and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of papers that comprehensively describe the major areas of research on lipid metabolism of plants. State-of-the-art knowledge about research on fatty acid and glycerolipid biosynthesis, isoprenoid metabolism, membrane structure and organization, lipid oxidation and degradation, lipids as intracellular and extracellular messengers, lipids and environment, oil seeds and gene technology is reviewed. The different topics covered show that modern tools of plant cellular and molecular biology, as well as molecular genetics, have been recently used to characterize several key enzymes of plant lipid metabolism (in particular, desaturases, thioesterases, fatty acid synthetase) and to isolate corresponding cDNAs and genomic clones, allowing the use of genetic engineering methods to modify the composition of membranes or storage lipids. These findings open fascinating perspectives, both for establishing the roles of lipids in membrane function and intracellular signalling and for adapting the composition of seed oil to the industrial needs. This book will be a good reference source for research scientists, advanced students and industrialists wishing to follow the considerable progress made in recent years on plant lipid metabolism and to envision the new opportunities offered by genetic engineering for the development of novel oil seeds.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many studies have shown that free radical damage and lipid peroxidation increase as a function of the degree of unsaturation of the fatty acids present in the phospholipids of biological membranes. Membrane phospholipids are particularly susceptible to oxidation not only because of their highly polyunsaturated fatty acid content but also because of their association in the cell membrane with non-enzymatic and enzymatic systems capable of generating pro-oxidative-free radical species. There are two broad outcomes to lipid peroxidation: structural damage to membranes and generation of secondary products. Membrane damage derives from the generation of fragmented fatty acyl chains, lipidlipid cross-links, lipidprotein cross-links and endocyclisation to produce isoprostanes and neuroprostanes. These processes combine to produce changes in the biophysical properties of membranes that can have profound effects on the activity of membrane-bound proteins. The consequence of peroxidation of unsaturated fatty acids is severe: damage of membranes function, enzymatic inactivation, toxic effects on the cellular division, etc. This new book presents and discusses current research on oxidative stress, and lipid oxidation non-inhibited and inhibited; assessment of oxidative balance in the lipo- and hydro-philic cellular environment in biological systems; mass spectrometry detection of protein modification by cross-reaction with lipid peroxidation products; diagonal gel electrophoretic analysis of protein disulfides: principles and applications. Other chapters describe: heavy metals exposure and cells oxidative damage; biodegradation of metallic biomaterials: its relation with the generation of reactive oxygen species; Oxidative modifications of proteins in the aging heart; role of reactive oxygen species as signalling molecules involved in the regulation of physiological processes of the nervous system; oxidative stress in diabetes and hypertension treated with alternative therapy of medicinal plants; impairment of redox homeostasis of tissue damage in inborn errors of metabolism with intoxication: insights from human and animal studies and finally lipid peroxidation of phospholipids in the vertebrate retina or in liposomes made of retinal lipids: similarities and differences are described.
