From: Comprehensive lipid analysis of human meibum and tears
WmE composition of human meibum and tears. Lipids were extracted from meibum and tears collected from healthy subjects (n = 7), and WmEs were analyzed via LC-MS/MS in MRM mode. (a and b) Total quantities of C16:1 FA- or C18:1 FA-containing WmEs in meibum (a) and tears (b), according to the saturation or mono-unsaturation of their FAl moieties. Values are presented as mean + SD. (c) FAl moiety composition of C16:1 FA- or C18:1 FA-containing WmEs, in pie charts. Species present at < 1% were categorized as “Others”. The simplified structure of WmE, showing the analyzed moiety, is represented. Sat, saturated; MonoU, mono-unsaturated.
