Elaidic acid is the major trans fat found in hydrogenated vegetable oils and occurs in small amounts in caprine and bovine milk (very roughly 0.1% of the fatty acids) [1] and some meats. It is the trans isomer of oleic acid. The name of the elaidinization reaction comes from elaidic acid.

Elaidic acid increases plasma CETP activity which lowers HDL cholesterol.[2]
