Definitions
Oxidized (Phospho)lipids – molecular species generated from (poly)unsaturated diacyl- and alk(en)ylacyl phospholipids via enzymatic and non-enzymatic oxidation.
Synonyms
Oxidized glycerophospholipids, oxPL (abbr)
Oxidized glycerophospholipids, previously seen mainly as a toxic byproduct of free radical reactions, nowadays are recognized as an important mediator of various cellular responses and play a significant role in organism redox balance. Early studies mainly focused on free fatty acid (FFA)-derived lipid peroxidation products (LPPs), especially iso- and neuroprostanes, established them as biomarkers of inflammatory pathways in mammals. Recently, structural and biological activity studies have been translated from FFA-derived LPPs to oxidized phospholipids (oxPLs). oxPLs have been shown to play a significant role in various and often controversial biological functions including pro- and anti-inflammatory pathways, cell death signaling, and pro-survival effects (Greiq...
