a
Compound identification denotes systematic and common name for quick indication.
b
According to the LIPID MAPS system. GP abbreviations refer to species with one or two side-chains where the structures of the side chains are indicated within parentheses in the “headgroup(sn-1/sn-2)” format. Acyl chains are assumed by default. The “O-” prefix indicates the presence of an alkyl ether substituent; the “P-” prefix is used for the 1Z-alkenyl ether (plasmalogen) substituent.
c
Nonitalic lowercase letters in this column denote UPLC conditions a and b as in Materials and Methods.
