This paper describes the use of positive and negative ion electrospray mass spectrometry (MS) and MS/MS (tandem mass spectrometry) to identify glycerophospholipid and ceramide headgroups and their alkyl, alkenyl and acyl constituents. Molecular ion adducts were the primary products formed by positive ionization, occurring as [M+H]+, [M+Na]+, [M+K]+, [M+formate]+, or [M+acetate]+, depending upon the class of glycerophospholipid and the presence or absence of these ionization-promoting species… CONTINUE READING
