n.
1. A trans fatty acid.
2. Trans fatty acids considered as a group.

trans fat

An unsaturated fat containing a trans—i.e., the carbon moieties on the two sides of the double bond point in opposite directions—(E)- isomer. Trans fats (TFs) are not found in nature; minimal TFs are present in animal fats. TFs are abundant in margarines, frying fats and shortenings, and are formed when polyunsaturated fat-rich vegetable and marine oils and vegetable shortenings are “hardened” by partial hydrogenation, producing fats with a firmness and consistency desired by both food manufacturers and consumers. The most abundant TF is elaidic acid and its isomers, which are 18-carbon molecules with one double bond.

TFs comprise 6 to 8% of the daily per capita consumption of fat in developed nations; health experts recommend reduction of TFs to trace amounts, as increased dietary TFs result in increased total and LDL-cholesterol, reduced HDL-cholesterol and an increased risk of coronary artery disease.

trans fat

A fat derived from the partial hydrogenation of vegetable oils. Examples include vegetable shortening and margarine. Studies have associated trans-fat consumption with an increased risk for coronary artery disease.

Relative to trans fatty acids, the researchers' attention for their adverse effects was raised by the work of Mensink and Katan (1990), who demonstrated that the ingestion of large amounts of trans fatty acids increased the levels of low density lipoprotein (LDL), similarly to saturated fatty acids.
