Abstract
The presence of a new ceramide subclass, the 1-O-acyl omega-linoleoyloxy ceramides [1-O-E (EO) Cer], has been previously highlighted in reconstructed human epidermis (RHE). These ceramides are double esterified on two positions. The first is the 1-O position of the sphingoid base moiety with a long to very long chain of acyl residues (1-O-E), and the second is the position of the ω-hydroxyl group of the fatty acid moiety with linoleic acid (EO). Considering its chemical structure and hydrophobicity, this subclass can contribute to the skin barrier. Thus, it is important to determine whether this subclass is also present in native human stratum corneum (SC). This work compares ceramide structures of this novel subclass between RHE (in vitro) and two sources of human SC (in vivo and ex vivo) using normal-phase high-performance liquid chromatography coupled to high-resolution mass spectrometry (NP-HPLC/HR-MSn). The results confirm the presence of this double esterified ceramide subclass [1-O-E (EO) Cer] in human SC. The molecular profile obtained from the RHE was very close to that found in the human SC (in vivo and ex vivo). In addition, thanks to the targeted MS2/MS3 analysis, a new ceramide subclass was discovered and characterized in the three studied samples. We propose to name it [A-1-O-E (EO) Cer] because in these ceramides species, the fatty acid—esterified with the sphingoid base on the 1-O position—is hydroxylated on the α position. These results highlight the potential of both the analytical method and the characterization approach employed in this study.
