Eicosatrienoic acid (20:3, ETA)
MetabolismEicosatrienoic acid is an intermediate omega-3 fatty acid formed during the conversion of ALA to EPA.
It contributes to anti-inflammatory lipid signaling pathways.
Why this matters
Although present in small amounts, ETA helps regulate inflammation and vascular tone. Higher levels may reflect efficient omega-3 metabolism and support cardiovascular protection.
How this connects to other biomarkers
- Eicosatrienoic Acid is a minor n-3/n-9 metabolite typically interpreted in the context of the full fatty acid panel; isolated changes have limited clinical significance.
