We therefore propose that the presence of ethyl DHA and ethyl linolenate in meconium may be significant because the esterification of DHA acid and α-linolenic acid by alcohol may promote the excretion of these important fatty acids as soluble ethyl esters, ultimately limiting the availability of DHA for fetal brain development and therefore acting as a potential mechanism of the fetal alcohol syndrome or other fetal alcohol spectrum disorders.

In most naturally-occurring unsaturated fatty acids, each double bond has three n carbon atoms after it, for some n, and all are cis bonds. A trans fatty acid or “trans fat” is an unsaturated fatty acid molecule that contains a trans double bond between carbon atoms. Trans fats may be monounsaturated or polyunsaturated, but are never saturated.
