N-palmitoyl-D-erythro-sphingosylphosphorylcholine (16:0 SM (d18:1/16:0)) has been used as a standard for the quantitation of sphingolipid metabolites. It has also been used for the quantification of lipids in green fluorescence protein (GFP) and fatty acid transport protein 4 (FATP4) cells using electrospray ionization tandem mass spectrometry (ESI-MS/MS). It may be used in liposomes to measure ostreolysin A (OlyA) binding to determine the effects of phosphatidylcholines (PCs) on sphingomyelin (SM)/cholesterol interactions.
