Elaidic acid

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). It is the trans isomer of oleic acid. The name of the elaidinization reaction comes from elaidic acid.

Elaidic acid increases CETP activity, which in turn raises VLDL and lowers HDL cholesterol.
