摘要

Background: Sphingomyelin (SM) is a key component of extracellular membranes and lipoproteins, and plays roles in cell signaling and as a component of lipoproteins. SM species differ in terms of fatty acid (FA) composition. However, no simple, rapid, quantitative assay for identifying different SM species has yet been reported. In this study, lipid hydrolase treatment and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) were used to identify serum SM species.
