FMOCAnalysis of lipid remodeling can be achieved by monitoring the lyso metabolites of ethanolamine glycerophospholipids. However, mass spectrometric analyses cannot distinguish between alkenyl and alkyl lysoglycerophosphoethanolamines without chromatography. In this chapter, we describe the use of fluorenyl...
