Discovering novel brain lipids by liquid chromatography/tandem mass spectrometry Guan ZJ Chromatogr B Analyt Technol Biomed Life Sci 2009[Sep]; 877 (26): 2814-21Discovery and structural elucidation of novel brain lipids hold great promise in revealing new lipid functions in the brain and in understanding the biochemical mechanisms underlying brain physiology and pathology. The revived interests in searching for novel brain lipids have been stimulated by the expanding knowledge of the roles of lipids in brain functions, lipids acting as signaling molecules, and the advent of lipidomics enabled by the advances in mass spectrometry (MS) and liquid chromatography (LC). The identification and characterization of two classes of novel lipids from the brain are reviewed here: N-acyl phosphatidylserine (N-acyl-PS) and dolichoic acid (Dol-CA). The identification of these lipids benefited from the use of efficient lipid fractionation and separation techniques and highly sensitive, high-resolution tandem MS.|*Brain Chemistry[MESH]|Animals[MESH]|Brain/metabolism[MESH]|Chromatography, Liquid/*methods[MESH]|Humans[MESH]|Lipid Metabolism[MESH]|Lipids/*chemistry/isolation & purification[MESH]|Tandem Mass Spectrometry/*methods[MESH] |
