With the advantage of MS2 fragmentation glycerophospholipids and glycerolipids (except TAG) are reported as subspecies, giving additional information on fatty acids – e.g. PI 18:1;0_16:0;0 denotes phosphatidylinositol with octadecenoic (18:1;0) and hexadecanoic (16:0;0) fatty acids, for which the exact position (sn-1 or sn-2) in relation to the glycerol backbone cannot be discriminated. PE O-18:1;0/16:0;0 denotes an ether-phosphatidylethanolamine, where an alkyl chain with 18 carbon atoms and 1 double bond (O-18:1;0) is ether-bound to sn-1 position of the glycerol and a hexadecanoic acid (16:0;0) is connected via an ester bond to the sn-2 position of the glycerol. The remaining lipid classes are reported as species – e.g. TAG 56:3;0 denotes triacylglycerol with the total length of its fatty acids of 56, 3 double bonds, and 0 hydroxylations.
