Unlocking the Trans-Isomer of Linolenic Acid

18:3 t is scientifically identified as linolenelaidic acid or linolenelaidate. It represents the trans-isomer counterpart of linolenic acid 18:3. (source )

Isomers, like 18:3 t, are compounds that share identical chemical formulas but differ in their structural arrangements.

The cis-isomer indicates that functional groups are located on the same side of the carbon chain, whereas the trans-isomer indicates that these groups are situated on opposing sides of the carbon chain. (source )

Linolenelaidic Acid's Connection to Inflammation

Linolenelaidic acid has been identified as a pro-inflammatory agent, which means it has properties that can promote inflammation in the body.

However, the intriguing aspect of this fatty acid is that its effects are balanced by the presence of cis-isomers.

When the proportion of cis-isomers increases, the anti-inflammatory activity rises, making it a fascinating subject of study in the field of nutrition and health.
