Metabolite Identification
Common NameEthyl hexadecanoate
DescriptionEhtyl hexadecanoate is the ester formed by the condensation of hexadecanoic acid and ethanol. Ethyl hexadecanoate is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Ethyl hexadecanoate can be found in alcoholic beverages. It is also present in various fruits, e.g. apricot, sour cherry, grapefruit, bilberry, guava fruit, melon, pineapple, Chinese quince, ceriman (Monstera deliciosa) etc. As well as in crispbread, clary sage, blackcurrant buds, wines, rice bran, plum brandy, fruit brandy, Bourbon vanilla, beans and salted/pickled plum.
