trans fatty acid

n.
An unsaturated fatty acid produced by the partial hydrogenation of vegetable oils and present in hardened vegetable oils, most margarines, commercial baked foods, and many fried foods. An excess of these fats in the diet is associated with high LDL cholesterol levels, low HDL cholesterol levels, and an increased risk of coronary heart disease.
