Elaidinic acid or elaidic acid or, again, trans-oleic acid and whose term in the official IUPAC nomenclature is: trans-9-octadecenoic acid is a naturally occurring fatty acid.
Elaidinic acid has a brute or molecular formula: C18H34O2.
This compound is an 18 carbon monounsaturated trans fatty acid in position 9. It is the isomer of oleic acid.
Elaidinic acid is present in nature, like other trans or conjugated fatty acids, and is formed by the biohydrogenation process due to bacteria, normally gram negative, in an anaerobic environment.
It is also found in pomace oil due to the isomerization of oleic acid during the drying of pomace in metal containers that catalyze the reaction.
Elaidinic acid is found naturally in small quantities also in goat and bovine milk (about 0.1% of fatty acids) and in some meats. It contains about 2.50% of the fats of the durian fruit (Durio graveolens Becc., 1889).
Among the properties of elaidinic acid, it should be remembered that it increases the activity of the plasma cholesterol transfer protein (CETP) which lowers HDL cholesterol.
Elaidinic acid was first identified by the French pharmacist, Poutet JJE, who gave it the name: acid élaidique by Boudet, who called elaidine, the hydrogenation product of trioleins.
