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