trans-dienoic fatty acids are polyunsaturated trans fatty acids with at least one double bond in the trans configuration.
Natural dienoic fatty acids are found in meat and dairy products. But also in marine invertebrates, like mollusks, and cephalopods.
trans-fatty acids, that have been hydrogenated have shown to increase the risk of cardiovascular disease.

In The Diene System
trans-Dienoic fatty acids are fatty acids within the conjugated diene system. (source) A diene is a compound that contains two double bonds, usually among carbon atoms.
Where To Find trans-Dienoic Fatty Acids
You can find trans-dienoic fatty acids in meat and dairy products. The main isomer is about 1% of the fatty acids of milk fat.(source)
Long-chain conjugated dienoic fatty acid can be found in plant sources. Conjugated dienoic fatty acids in refined oils are mainly the product of processing. (source)
Common dienoic acids:
- cis-9,12-octadecadienoic acid (lioleic acid)
- trans-9,12-octadecadienoic acid (linelaidic acid)
- 5,9-heneicosadienoic acid
- 5,9-docosadienoic acid
- 5,9-tricosadienoic acid
