16:0-18:1 Phosphatidylethanol 840514 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanol (sodium salt)
Phosphatidylethanol (PEth) represents a group of glycerophospholipid homologues generated by substitution of ethanol for the lipid headgroup by the phospholipase D enzyme.Since the formation of PEth is specifically dependent on ethanol, the diagnostic specificity of PEth as an alcohol biomarker is theoretically 100%.
