This book brings 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.
Robert C Murphy graduated from Massachusetts Institute of Technology with a PhD in chemistry and he is currently a University Distinguished Professor at the University of Colorado. He has worked in the area of mass spectrometry and eicosanoid biochemistry for approximately 40 years with much of his research activities centered on the use of mass spectrometry to studies of arachidonic acid biochemistry and formation of the biologically active leukotriene mediators. His interests also include the structural characterizaton of bioactive lipid products derived from the reaction of reactive oxygen species with cellular lipids. Over 400 peer-reviewed papers in scientific journals and several books concerning mass spectrometry of lipids have been authored by him.
