How are trans fatty acids produced and are they healthy?
What will be an ideal response?
ANS: Trans fatty acids are produced by the hydrogenation of unsaturated fatty acids causing them to become more saturated. Hydrogenation involves heating an oil and exposing it to hydrogen gas to break double bonds and add hydrogen. During the process, the hydrogens cross to opposite sides of the carbon chain, resulting in a trans configuration. Trans fatty acids act more like saturated fatty acids and thus are unhealthy for you.
