General description

Phosphatidylethanol (PEth) is a phospholipid, that is generated in the the presence of ethanol in cell membranes. PEths like PEth 16:0/18:1, PEth 18:1/18:1, and PEth 16:0/16:0 possesses a common phosphoethanol head. Two fatty acid chains of variable length and degree of saturation are bound to this head group.

Application

16:1 Phosphatidylethanol is suitable to use as a standard for the quantification of PEths in whole blood and in venous or capillary dried blood spots (DBS).

Biochem/physiol Actions

Phosphatidylethanols (PEths) serves as crucial biomarkers of alcohol consumption.
