This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical properties of glycerophospholipids (GPLs) are not only determined by the head group (HG), but also by their fatty acid (FA) chains, which affect their distribution and function within membranes in the cell. Understanding the microheterogenity of lipid membranes on a molecular level requires qualitative and quantitative characterization of individual lipids and identification of their FA moieties. The aim of my study was to introduce the new technology of multiple precursor ion scanning (MPIS) on a QSTAR Pulsar time-of-flight mass spectrometer (QqTOF) to analyze lipids. Detailed information on fatty acid composition of individual GPL molecules could be obtained in parallel with conventional profiling of lipid classes, and this could be done by direct analysis of total lipid extracts. This method was termed Fatty Acid Scanning (FAS) and Head Group Scanning HGS, respectively. In this way the molecular GPL composition of total lipid extracts could be charted in a single analysis accurately and rapidly at a low picomole concentration level. Furthermore, combining FAS and HGS together with ion trap MS3 analysis allowed complete charting of the molecular composition of PCs, including quantification of their positional isomers, thus providing a detailed and comprehensive characterization of molecular composition of the pool of PCs. Development of the Lipid Profiler software allowed full automation and rapid processing of complex data, including identification and quantification of molecular GPLs. This approach was evaluated by preliminary applications. First, the molecular composition of PCs of total lipid extracts of MDCK cells and of human red blood cells (RBC) could accurately be charted. Significant presence of positional isomers was observed increasing the total number of individual PC species close to one hundred. Secondly, the molecular PC and SM species distribution in detergent resistant membranes (DRMs) prepared by Triton X-100 DRMs were analyzed and.

Available in PDF, EPUB and Kindle. Book excerpt: Cells, whether bacterial, fungal or mammalian, are all equipped with metabolic pathways capable of producing an assortment of structurally and functionally distinct lipid species. Despite the structural diversity of lipids being recognized and correlated to specific cellular phenomena and disease states, the molecular mechanisms that underpin this structural diversity remain poorly understood. In part, this is due to the lack of adequate analytical techniques capable of measuring the structural details of lipid species in a direct, comprehensive and quantitative manner. The aim of my thesis study was to establish methodology for automated and quantitative analysis of molecular lipid species based on mass spectrometry. From this work a novel high-throughput methodology for lipidome analysis emerged. The main assets of the methodology were the structure-specific mass analysis by powerful hybrid mass spectrometers with high mass resolution, automated and sensitive infusion of total lipid extracts by a nanoelectrospray robot, and automated spectral deconvolution by dedicated Lipid Profiler software. The comprehensive characterization and quantification of molecular lipid species was achieved by spiking total lipid extracts with unique lipid standards, utilizing selective ionization conditions for sample infusion, and performing structure-specific mass analysis by hybrid quadrupole time-of-flight and ion trap mass spectrometry. The analytical routine allowed the comprehensive characterization and quantification of molecular glycerophospholipid species, molecular diacylglycerol species, molecular sphingolipid species including ceramides, glycosphingolipids and inositol-containing sphingolipids, and sterol lipids including cholesterol. The performance of the methodology was validated by comparing its dynamic quantification range to that of established methodology based on triple quandrupole mass spectrometry. Furthermore, its efficacy for lipidomics projects was demonstrat.
Book Synopsis Tandem Mass Spectrometry of Lipids by : Robert C Murphy
Download or read book Tandem Mass Spectrometry of Lipids written by Robert C Murphy and published by Royal Society of Chemistry. This book was released on 2014-12-15 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emerging field of lipidomics has been made possible because of advances in mass spectrometry, and in particular tandem mass spectrometry of lipid ions generated by electrospray ionization. The ability to carry out basic biochemical studies of lipids using electrospray ionization is predicated upon understanding the behaviour of lipid derived ions following collision induced decomposition and mechanisms of product ion formation. During the past 20 years, a wealth of information has been generated about lipid molecules that are now analysed by mass spectrometry, however there is no central source where one can obtain basic information about how these very diverse biomolecules behave following collisional activation. This book will bring together, in one volume, this information so that investigators considering using tandem mass spectrometry to structurally characterize lipids or to quantitate their occurrence in a biological matrix, will have a convenient source to review mechanism of decomposition reactions related to the diversity of lipid structures. A separate chapter is devoted to each of seven major lipid classes including fatty acids, eicosanoids and bioactive lipid mediators, fatty acyl esters and amides, glycerol esters, glycerophospholipids, sphingolipids, and steroids. Mechanistic details are provided for understanding the pathways of formation of major product ions and ions used for structural characterization. In most cases specific ancillary information has been critical to understand the pathways, including isotope labeling and high resolution analysis of precursor and product ions. For a few specific examples such data is missing and pathways are proposed as a means to initiate further mass spectral experiments to prove or disprove pathway hypotheses. While this work largely centres on the lipid biochemistry of animal (mammalian) systems, general principles can be taken from the specific examples and applied to lipid biochemistry found in plants, fungi, prokaryotes and archeal organisms.

Available in PDF, EPUB and Kindle. Book excerpt: Metabolomics, the global characterisation of the small molecule complement involved in metabolism, has evolved into a powerful suite of approaches for understanding the global physiological and pathological processes occurring in biological organisms. The diversity of metabolites, the wide range of metabolic pathways and their divergent biological contexts require a range of methodological strategies and techniques. Methodologies for Metabolomics provides a comprehensive description of the newest methodological approaches in metabolomic research. The most important technologies used to identify and quantify metabolites, including nuclear magnetic resonance and mass spectrometry, are highlighted. The integration of these techniques with classical biological methods is also addressed. Furthermore, the book presents statistical and chemometric methods for evaluation of the resultant data. The broad spectrum of topics includes a vast variety of organisms, samples and diseases, ranging from in vivo metabolomics in humans and animals to in vitro analysis of tissue samples, cultured cells and biofluids.
