Websulfuric acid (1 in 2), add a slight excess of acid, heat with gentle stirring until the fatty acid layer separates. Transfer the fatty acids into a warm 500-ml separatory funnel, wash with four 20-ml portions of hot water and combine the washings with the original aqueous layer from the saponification. WebFatty Acid Ethyl Esters. Fatty acid ethyl esters (FAEE) are formed by an enzyme-mediate esterification of ethanol with fatty acids or fatty acyl-coenzyme A. It has been shown that FAEE and the FAEE synthase are predominantly present in those organs most often damaged by ethanol abuse, notably the pancreas and liver.
