  1. The relative abundance of PC, triglycerides and diglycerides (which represent fragmented triglycerides) were grouped based on whether they contain a LC-PUFA. LC-PUFA-containing PCs were assigned based on targeted LC-MS/MS analysis (Supplementary Data Table S6). Triglyceride signals with 54 or more carbons and 5 or more double-bonds, and diglyceride signals with 38 or more carbons and 5 or more double-bonds, were expected to contain a LC-PUFA. Data is presented in the positive ionisation mode to highlight the proportion of LC-PUFAs in triglycerides compared to PC. Data is combined for pregnant (15.5 dpc; groups 2, 8 and 5) and virgin (groups 1, 6 and 3) groups and presented as mean relative abundance ( ± SD). Plasma data: n = 7 (group 1), n = 7 (group 2), n = 7 (group 3), n = 6 (group 5), n = 5 (group 6), n = 7 (group 8); Liver data: n = 8 (group 1). n = 7 (group 2), n = 7 (group 3), n = 8 (group 5), n = 7 (group 6), n = 8 (group 8). DG diglyceride, LC-PUFA long-chain polyunsaturated fatty acid, PC phosphatidylcholine, PE phosphatidylethanolamine, TG triglyceride. Source data are provided as a Source Data file.
