Sphingolipid diversity and profiling in selected Caryophyllales species

Abstract

Sphingolipid composition was compared among selected Caryophyllales species using LC–MS/MS. Glycosylinositol phosphorylceramide molecular species profiles differed between AC and SB groups, accompanied by variation in glycan series distribution and the GIPC/GlcCer ratio. Differences in sphingoid base modification and ceramide structure were also observed, suggesting group-associated differences in sphingolipid metabolism and potential value for future chemotaxonomic studies.
