C16-02:0 PC, also referred as 1-O-hexadecyl-2-acetyl-sn-glycero-3-phosphocholine (C16 PAF) (acetyl PAF), is a platelet-activating factor (PAF). Acetyl PAF is a natural PAF with ether-linked hexadecyl chain at the sn-1 position and an acetyl group at the sn-2 position. Application： C16-02:0 PC or 1-O-hexadecyl-2-acetyl-sn-glycero-3-phosphocholine may be used as a substrate in enzymatic lipoprotein-associated phospholipase A2 (Lp-PLA2) activity assay. It may also be used to study its physicochemical properties and its interaction with peptides derived from the C-terminal domains of human apolipoprotein E.
