| fatty acid analysis by gc: Lipid Analysis W. W. Christie, X Han, 2010-01-10 This well-known and highly successful book was first published in 1973 and has been completely re-written in subsequent editions (published in 1982 and 2003). This new Fourth Edition has become necessary because of the pace of developments in mass spectrometry of intact lipids, which has given recognition of lipid analysis and ‘lipidomics’ as a distinct science. To bring the book up to date with these developments, author William W. Christie is joined by co-author Xianlin Han. Although devoting considerable space to mass spectrometry and lipidomics, Lipid analysis remains a practical guide, in one volume, to the complexities of the analysis of lipids. As in past editions, it is designed to act as a primary source, of value at the laboratory bench rather than residing on a library shelf. Lipid analysis deals with the isolation, separation, identification and structural analysis of glycerolipids, including triacylglycerols, phospholipids, sphingolipids, and the various hydrolysis products of these. The chapters follow a logical sequence from the extraction of lipids to the isolation and characterization of particular lipid classes and of molecular species of each, and to the mass spectrometric analysis of lipids and lipidomics. The new influence of mass spectrometry is due mainly to the development of electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). Most emphasis in this book is placed on ESI, which is enabling structural characterization of different lipid classes and the identification of novel lipids and their molecular species. |

| fatty acid analysis by gc: Analysis of Sterols J. Goad, T. Akihisa, 2012-12-06 Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it Samuel Johnson, 18 April, 1775* Sterols are among the most studied groups of natural products with interest commencing in the 19th century and running to the present. Investigations have embraced the refinement of separation procedures, the development of new analytical techniques and instrumentation for structure elucidation, the unravelling of biosynthetic mechanisms, the determination of the physiological functions of sterols, and the role they play in health and disease. In the past 20-30 years interest in the medical implications of sterol biochemistry, studies on the sterols of plants, algae and fungi, and the identification of the many unusual sterols from marine organisms have proceeded in parallel and somewhat independently. Although the motiva tion and goals for the various lines of investigation have differed widely the researchers working in each of these areas have contributed a wealth of knowledge to the literature relating to the analysis of sterols and many diverse new sterols have been discovered. We conceived this book as a modest attempt to bring together some of this literature in the hope that it may be helpful to newcomers to sterol research. We had originally intended to produce a 'handbook' outlining in detail the protocols to be followed for sterol extraction, chromatography, NMR analysis, etc. in order to identify the components of a sterol mixture. |

| fatty acid analysis by gc: Lipid Oxidation Edwin N. Frankel, 2014-01-23 In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems. The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease. Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals. |

| fatty acid analysis by gc: Molecular Microbial Ecology Manual Antoon D. L. Akkermans, Jan Dirk Van Elsas, Frans J. De Bruijn, 2014-01-13 For a long time microbial ecology has been developed as a distinct field within Ecology. In spite of the important role of microorganisms in the environment, this group of 'invisible' organisms remained unaccessable to other ecologists. Detection and identification of microorganisms remain largely dependent on isolation techniques and characterisation of pure cul tures. We now realise that only a minor fraction of the microbial com munity can be cultivated. As a result of the introduction of molecular methods, microbes can now be detected and identified at the DNA/RNA level in their natural environment. This has opened a new field in ecology: Molecular Microbial Ecology. In the present manual we aim to introduce the microbial ecologist to a selected number of current molecular techniques that are relevant in micro bial ecology. The first edition of the manual contains 33 chapters and an equal number of additional chapters will be added this year. Since the field of molecular ecology is in a continuous progress, we aim to update and extend the Manual regularly and will invite anyone to depo sit their new protocols in full detail in the next edition of this Manual. We hope this book finds its place where it was born: at the lab bench! Antoon D.L.

| fatty acid analysis by gc: Process-Induced Chemical Changes in Food Fereidoon Shahidi, Chi-Tang Ho, Nguyen Van Chuyen, 1998-04-30 Chemical changes that occur in foods during processing and storage are manifold and might be both desirable and undesirable in nature. While many of the processes are carried out intentionally, there are also certain unwanted changes that naturally occur in food and might have to be controlled. Therefore, efforts are made to devise processing technologies in which desirable attributes of foods are retained and their deleterious ef fects are minimized. While proteins, lipids and carbohydrates are the main nutrients of food that are affected by processing, it is their interaction with one another, as well as in volvement oflow-molecular-weight constituents that affects their flavor, color and overall acceptability. Thus, generation of aroma via thermal processing and bioconversion is of utmost importance in food preparation. Furthermore, processing operations must be opti mized in order to eliminate or reduce the content of antinutrients that are present in foods and retain their bioactive components. Therefore, while novel processing technologies such as freezing, irradiation, microwaving, high pressure treatment and fermentation might be employed, control process conditions in a manner that both the desirable sensory attributes and wholesomeness of foods are safeguarded is essential. Obviously, method ologies should also be established to quantitate the changes that occur in foods as a result of processing. This volume was developed from contributions provided by a group of internation ally-recognized lead scientists. |

| fatty acid analysis by gc: Analytical Microbiology Methods A. Fox, L. Larsson, S.L. Morgan, G. Odham, 2013-11-11 The First International Symposium on the Interface between Analytical Chemistry and Microbiology: Applications of Chromatography and Mass Spectrometry was held June 1987 at the University of South Carolina, Columbia, SC, U.S.A. The purpose of the Interface meeting was to forge connections between analytical chemists and microbiologists that are using chromatography and mass spectrometry to solve common problems. The goals were admirably fulfilled. Nearly a hundred participants from seven European countries, Japan, and the United States participated in hearing twenty-three plenary talks and thirty-six submitted papers and posters. The papers and discussions displayed the breadth and depth of current research applications and revealed future directions. This book Analytical Microbiology Methods: Chromatography and Mass Spectrometry is loosely based on some of the presentations and discussions at the meeting. Each chapter describes specific methodology and applications in the context of the relevant scientific background. The present book continues the theme of an earlier book, Gas Chromatography/Mass Spectrometry Applications in Microbiology, edited by G. Odham, L. Larsson, and P-A. Mardh, published by Plenum Press in 1984. |
| fatty acid analysis by gc: Atherosclerosis: Diet and Drugs Arnold von Eckardstein, 2005-05-13 Cardiovascular diseases continue to be the leading cause of death in the - jority of industrialized countries. The most frequent underlying pathology, namely atherosclerosis, and its clinical sequelae, namely coronary heart d- ease, cerebrovascular disease and peripheral artery disease, remain common although for a long time we have been made aware of avoidable or mo- ?able etiological factors such as smoking, fat-rich diet or lack of exercise, and although these adverse lifestyle factors have been extensively addressed by population-wide primary prevention programs. Cardiovascular morbidity and mortality also remain high despite successful anti-hypertensive and lipid lowering drug therapies which help to reduce cardiovascular morbidity and mortality by about 30% in both secondary and tertiary prevention settings. This can partly be explained by the increasing life expectancy and growing p- portionofelderly people,especiallyinEuropeandNorthAmerica. Inaddition, the World Health Organization makes the alarming prediction that probably in response to the spreading of western dietary behavior and lack of exercise resulting in an increasing prevalence of diabetes, dyslipidemia and hypert- sion, cardiovascular diseases rather than infectious diseases will become the most frequent cause of death worldwide. This volume of the Handbook of Experimental Pharmacology entitled “Atherosclerosis” is divided into four parts and intends to give an overview on the pathogenesis of atherosclerosis, established treatment and prevention regimen, and of perspectives for the development of new treatment modalities. |
