Total number of peaks identified for each lipid sub-class, for which the sum composition (i.e., the identity of the individual headgroup and the combined total number of carbons and double bonds within the acyl, alkyl and/or alkenyl chains) could be assigned from the mass spectra.
Identified lipids categorizes those species whose molecular lipid identities of their individual fatty acyl, alkyl and/or alkenyl chains could be determined by MS/MS.
Total lipids includes the combined number of lipids whose identities of their individual fatty acyl, alkyl and/or alkenyl chains could be determined by MS/MS, as well as those lipids where only the total number of carbons and double bonds within the acyl, alkyl and/or alkenyl chains could be assigned from the mass spectra.
