Question
Trans-fatty acids are synthetic forms of fatty acids made from altered unsaturated fatty
acids. Trans-fatty acids are denser, solid at room temperature, and store more energy in
the same unit of volume than unsaturated fatty acids. The production of trans-fatty acids
involves the reorientation of one of the hydrogen atoms attached to a double-bonded car-
bon atom, as illustrated in the figure below.
