Notes: Oxidized low-density lipoprotein (oxLDL) particles contain low molecular weight species which are cytotoxic and pro-atherogenic.{9800} Many of these substances were isolated and purified from oxLDL and identified as phosphatidylcholine species containing a fragmented, oxidized short-chain fatty acid remnant at the sn-2 position.{9891} PAz-PC is one of the predominant oxLDL species and may be one of the important structural determinants of oxLDL.{10651}
