Supplemental Methods: Oxylipid sample preparation:

Supplemental Methods:
Oxylipid sample preparation: Plasma (200μL) was spiked with a 5 µL 0.2 mg/ml solution butylated
hydroxytoluene/EDTA in 1:1 meoh:water and a suite of 10 deuterated prostanoid, eicosanoids, and
octadecanoid surrogates (Supplemental Table S2). To release oxygenated lipids contained in ester linkages
these samples were then subjected to overnight hydrolysis in 1M methanolic sodium hydroxide1. Samples were
diluted to 10% methanol and extracted on 60mg Oasis HLB solid phase extraction columns (Waters, Milford,
MA), preconditioned with 5% methanol w/ 0.1% acetic acid, the loaded columns were washed with 1 column
volume of 5% methanol w/ 0.1% acetic acid, and dried for 30min under vacuum. Extracts were wetted with
0.5mL methanol and eluted with 2mL ethyl acetate into vials containing a 6µL of 30% glycerol keeper solvent,
and reduced to dryness under vacuum. We have confirmed oxylipid stability for >5months at -80ºC under these
conditions (unpublished data).
Oxylipin nomenclature: The International Union of Pure and Applied Chemistry (IUPAC) has adopted the
abbreviations for oxidized fatty acids following the recommendations of Smith et al.2, 3. Briefly, compounds are
named using position, number, and standardized abbreviations of functional groups, carbon chain length, and
degree of unsaturation. Plural chemical moieties are listed as Di (two), Tr (three), T (four), P (five), He (six).
Abbreviations of chemical moieties are: Ep – Epoxide; H – hydroxy; Hp – hydroperoxide; K – keto. Carbon
numbers appearing in this report are abbreviated O (octadeca i.e. 18), E (eicosa i.e. twenty) and Do (docosa i.e.
22). Therefore, 14(15)-epoxyeicostri-(5Z,8Z,11Z)-enoic acid is reduced to 14(15)-EpETrE while 9(10)epoxyoctadec-(12Z)-enoic acid becomes 9(10)-EpOME. Dihydroxy lipids are named similarly, such that 14,15dihydroxyeicostri-(5Z,8Z,11Z)-enoic acid becomes 14,15-DiHETrE, while 20-hydroxyeicosatetra(5Z,8Z,11Z,14Z)-enoic acid is 20-HETE.
