abstract::FA ethyl esters (FAEE) are nonoxidative metabolites of ethanol produced by the esterification of FA and ethanol. FAEE have been implicated as mediators of ethanol-induced organ damage in vivo and in vitro, and are markers of ethanol intake. Upon ethanol intake, FAEE are synthesized in the liver and pancreas in signifi...
