Fig. 5. Compositions of C18 sphingoid bases of GlcCer in PM and DRM fractions.

Fig. 5

Compositions of C18 sphingoid bases of GlcCer in PM and DRM were quantified by LC-MS/MS analysis. Y-axis of the graph indicates proportions of signals derived from each sphingoid base species in total GlcCer signals. Error bars indicate standard deviations (n=3). Z and E mean cis-8 and trans-8 isomers, respectively. d18:1, 8-sphingadienine; d18:2, 4,8-sphingadienine; t18:1, 4-hydroxy-8-sphingenine.
