Relative amounts of typical and atypical [13C]-labelled sphingoid bases produced by LY-B and LY-B/cLCB1 cells upon co-treatment with FB1. Shown are the relative ion intensities of the shown precursor/product pairs in the LC ESI-MS/MS eluates. The LC retention times for these species matched that of standards for these compounds (not shown). The samples for these analyses were obtained by incubating LY-B and LY-B/cLCB1 cells with 0.1 mM [13C]-palmitic acid and 25 μM FB1 for 24 h; the grey line indicates LY-B cells and the black line represents LY-B/cLCB1 cells.
