  1. (§) Putative Metabolites were identified through interpretation of tandem MS data. Feature identities were determined using a two-step approach described previously76: (1) search of public databases including METLIN, HMDB and Mass Bank using accurate mass and a mass error window of 10 ppm and (2) comparison of tandem MS data with available spectra for four important features followed by manual interpretation.
  2. (*) The metabolic processes indicated in this column are the processes that most closely associated with the detected metabolites. This means that the detected metabolites may be an intermediate, a product or derivatives of intermediates or products of the mentioned processes. The metabolic processes were identified based on available information in HMDB, Kegg database and Lipidomics Gateway. The compounds for which we could not find any information are denoted as ‘Unknown’.
