Phospholipid oxidation
WebNov 3, 2024 · Enzymatic oxidation or autooxidation of esterified polyunsaturated fatty acids (PUFA) residues within phospholipids in cell membranes or circulating lipoprotein particles leads to the formation of a broad range of oxidized phospholipid (OxPL) species. Webbind LPC. The results show that HDL-like phospholipid particles effectively inhibit the toxic effect of phospholipids and other lipid-soluble factors. The ability of HDL to inhibit the proinflammatory and toxic effects of phospholipids generated during oxidation of LDL may be responsible for part of the antiatherogenic properties of HDL.
