Peth

Answers From the Lab.

Phosphatidylethanols PEth are a group of phospholipids formed only in the presence of ethanol via the action of phospholipase D PLD. Chemically, phosphatidylethanols are phospholipids carrying two fatty acid chains , which are variable in structure, and one phosphate ethyl ester. When ethanol is present, PLD substitutes ethanol for water and covalently attaching the alcohol as the head group of the phospholipid; hence the name phosphatidylethanol. Normally PLD incorporates water to generate phosphatidic acid PA ; the process is termed transphosphatidylation. The lipid accumulates in the human body and competes at agonists sites of lipid-gated ion channels contributing to alcohol intoxication. Levels of phosphatidylethanols in blood are used as markers of previous alcohol consumption. However, it has been demonstrated that there can be significant inter-personal variation, leading to potential misclassification between moderate and heavy drinkers.
