Description
Lyso-PAF C-18-d4 contains four deuterium atoms at the 9, 9', 10, and 10' positions. It is intended for use as an internal standard for the quantification of Lyso-PAF C-18 by GC- or LC-mass spectrometry. Lyso-PAF C-18 can be formed by either the action of PAF-AH on PAF C-18 or by the action of a CoA-independent transacylase on 1-O-octadecyl-2-acyl-glycerophosphocholine.1,2,3 Lyso PAF C-18 is a substrate for either PAF C-18 formation by the remodeling pathway or selective acylation with arachidonic acid by a CoA-independent transacylase.4,5WARNING This product is not for human or veterinary use.
