The most abundant monoenoic fatty acids in animal and plant tissues are straight-chain compounds with 16 or 18 carbon atoms.

trans-fatty acids, that have been hydrogenated have shown to increase the risk of cardiovascular disease.

Harmful trans-Monoenoic Fatty Acids

The current nutritional view is that dietary trans-monoenoic fatty acids, especially those from industrial hydrogenation processes, should be considered as harmful. (source )

Industrial hydrogenation of vegetable oils is largely the main source of trans fatty acids in our diet. (source )

Examples of trans-monoenoic fatty acids:

  • Vaccenic acid 18:1-11 t (18:1t n-7)
  • Brassidic acid 22:1 t
