Molecular species concentrations of deuterated ceramides in the basolateral medium of Caco-2/TC7 cells. Deuterated ceramides (Cer-d9) molecular species concentrations in the basolateral medium of Caco-2/TC7 cells incubated for 16 h with mixed micelles enriched with sphingosine-d9 (MM + SPH-d9) or with sphingosine-d9 + C23:0 (MM + SPH-d9 + C23:0) (A) or with sphingosine-d9 + C22:0 (MM + SPH-d9 + C22:0) (B) or sphingosine-d9 + C18:0 (MM + SPH-d9+C18:0) (C). Cer-d9 molecular species annotations were based on the assumption that sphingosine d18:1 is the major sphingoid base. Data expressed as pmol/ml, represent the mean ± SEM of one experiment realized in quadruplicate. Asterisks represent a significant difference between MM + SPH and MM + SPH+FA (∗P < 0.05).
