'''Elaidic acid''' is the [[organic compound]] with the formula CH<sub>3</sub>(CH<sub>2</sub>)<sub>7</sub>CHCH(CH<sub>2</sub>)<sub>7</sub>CO<sub>2</sub>H. Classified as an [[Saturated fat|unsaturated]] [[trans fat|trans fatty acid]], it is a colorless oily solid. This compound has attracted attention because it is a major trans fat found in [[Hydrogenation|hydrogenated]] vegetable oils, and trans fats are implicated in heart disease.<ref>{{Cite journal | doi = 10.1017/S0954422411000011}}</ref> |

Elaidic acid is the organic compound with the formula CH3(CH2)7CHCH(CH2)7CO2H. Classified as an unsaturated trans fatty acid, it is a colorless oily solid. This compound has attracted attention because it is a major trans fat found in hydrogenated vegetable oils, and trans fats are implicated in heart disease.[1]
It is the trans isomerofoleic acid. The name of the elaidinization reaction comes from elaidic acid.
Elaidic acid occurs naturally in small amounts in caprine and bovine milk (very roughly 0.1% of the fatty acids)[2] and in some meats.[3]
Elaidic acid increases plasma cholesterylester transfer protein (CETP) activity which lowers HDL cholesterol.[4]
