Abstract

LC-MS is the method of choice to measure quantitative changes of hundreds of lipids in complex mixtures simultaneously. However,many lipid species are isobaric, resulting inambiguities about the true identity of the lipid in MS¹ data. MSⁿ spectra carry the potential to elucidate many structural features of lipid species: the lipid class, their constituent fatty acids, and in most cases the sn-position. However, MSⁿ spectra of a lipid can vary tremendously, because the fragmentation process depends on parameters such as mass spectrometer used, collision energy, and adduct ions. As currently available tools use static databases containing fragment masses,and are as such limited to specific instrumental-setups, we developed a flexible algorithm for automatic identification of lipid structures.
