Trans fatty acids are formed during hydrogenation, a process that solidifies liquid vegetable oils by adding hydrogen atoms to the double bonds of the unsaturated fatty acids in the trans instead of the cis position on the fatty acid molecule. The physical properties of trans fatty acids are like those of saturated fatty acids.

Trends in Food Science & Technology, 2010
By pumping hydrogen into edible oils (with heat and nickel catalyst) their fatty acids become more saturated and the oil solidifies. Hydrogenation was used from around 1912 to make the original margarines, which became the poor persons’ butter. If hydrogenation is not taken to completion and some double bonds remain, some of them now have their ...

Journal of Cardiopulmonary Rehabilitation, 2000
Trans fatty acids are unsaturated fatty acids that contain at least one double bond in the trans configuration. In the diet they occur at relatively low levels in meat and dairy products as a by-product of fermentation in ruminant animals or in hydrogenated fats as a consequence of the hydrogenation process.

Nutrition Reviews, 2009
Despite a general lack of evidence for the carcinogenic effects of trans fatty acids, some recent research and popular media have suggested a possible association. The available scientific data do not support this relationship and are reviewed so as to put this issue in perspective.

Metabolic aspects of trans fatty acids
Clinical Nutrition, 1997The consumption of trans isomers of unsaturated fatty acids has been associated withuntoward metabolic effects. Several clinical investigations demonstrated that trans fatty acids increase plasma LDL-cholesterol and lipoprotein (a) and reduce HDL-cholesterol concentrations.

Trans-Fatty Acids and Colon Cancer
Nutrition and Cancer, 2001Trans-fatty acids have been hypothesized to be carcinogenic, although there are limited data in humans testing this hypothesis. In this study, we examine the association between trans-fatty acids and colon cancer using data from a case (n = 1,993)-control (n = 2,410) study conducted in Utah, Northern California, and Minnesota.

Trans Fatty Acids and Cardiovascular Disease
Obstetrical & Gynecological Survey, 2006Trans fats-fatty acids having at lease one double bond in the trans configuration-form during partial hydrogenation of vegetable oils that is intended to convert them into semisolid fats to be used in commercial cooking. These products have a long shelf life, are stable during deep frying, and are semisolids that are conveniently used in baked goods ...
