Data processing of the 1,624 MS features acquired over the 48 LC-MS analysis of replicates of human plasma samples resulted in 1,124 MS features following filtering and removal of adducts, of which 428 were identified by MS/MS and 4 (indicated by *) with RT behavior. This table reports the number of lipids identified by category and (sub)classes. The complete list of identified lipids is provided in the Supplemental Excel file.
