Application

1-O-Palmityl-sn-glycero-3-phosphocholine also known as Lyso-PAF-(C16) can be used as a standard in the assay of platelet-activating factor.

Biochem/physiol Actions

Accumulation of lyso-PAF in atherogenic aortas may lead to unregulated PAF formation and can cause atherosclerosis.

Preparation Note

20mg of 1-O-Palmityl-sn-glycero-3-phosphocholine dissolves in 1 ml of water.

Other Notes

Inactive form of PAF[C16]

Suspensions of neonatal rat myocytes were used to investigate the metabolism of [3H]PAF (1-alkyl-2-acetyl-(sn-glycero-3-phosphocholine) (GPC] and [3H]alkyllyso-GPC. [3H]Alkylacyl-GPC consisting of molecular species with four or more double bonds (87%) was the major metabolite formed when either [3H]PAF (4 x 10(-6)

Multiple molecular species of the eosinophil chemoattractant platelet activating factor (PAF) are produced as a result of inflammatory processes. We therefore compared the ability of three naturally occurring PAF species (C16:0, C18:0, and C18:1), which only varied at carbon 1
