Recent developments in tandem mass spectrometry for lipidomic analysis

This review will focus on the role of mass spectrometry in the emerging field of lipidomics. Particular emphasis will be placed on recent developments in the use of tandem mass spectrometry methods in lipid analysis using low-energy collision induced dissociation (CID). After a brief discussion on ionization techniques, novel ion-activation methods that allow for increased sensitivity and selectivity will be critically discussed. Examples will be drawn from the analysis of higher order lipids, specifically triacylglycerols (TAGs) and glycerophospholipids, as the numerous positional isomers and head groups present in these classes of lipids continue to pose a significant analytical challenge to the field of lipidomics. The role of bioinformatics in the development of lipidomics will also be discussedPeer reviewed: YesNRC publication: Ye
