  1. aLipid names are listed as 2 or 3 letters for the class abbreviations followed by the number of carbon, a colon, and the number unsaturation in the fatty acyl chains (e.g. PC(32:3). PC- phosphatidylcholine, PCo - PC lipid with an alkyl ether substituent; PI - phosphatidylinositol, PIo: PI lipid with an alkyl ether substituent, PIp: PI lipid with a 1Z-alkenyl ether (plasmalogen) substituent, SM - sphyngomyelin, TAG - triacylglycerol. The TAG lipids were profiled using a product ion related to one of the fatty acyl chains since this lipid class has no polar head as the phospholipids or another specific functional group. The targeted fatty acyl chain is indicated after the TAG abbreviation by _FA carbon number:unsaturation (e.g. TAG(52:3)_FA 16:0
