FACTS ABOUT TRANS FATTY ACIDS

Fatty acids constitute the main class of lipids in the human diet, being found in nature mainly as glycerol esters that originate triacylglycerols. In the vegetal and animal kingdoms, fatty acids generally have cis unsaturations. In this form, the hydrogens bound to the double bond carbons are on the same side. In another possible configuration, called trans, the hydrogens are bound to un saturations, carbons on opposing sides. Fatty acids with one or more un saturations in the trans configuration are called trans fatty acids (TFAs).
