eikosapatiensyre

Eikosapentensyre, commonly abbreviated as EPA, is a type of omega-3 fatty acid. It is a polyunsaturated fatty acid with a chain of 20 carbon atoms and five double bonds. The "n-3" in its name indicates that the first double bond is located three carbon atoms from the methyl end of the fatty acid chain. EPA is considered an essential fatty acid for humans, meaning the body cannot synthesize it and must obtain it from the diet.

EPA is primarily found in fatty fish such as salmon, mackerel, herring, and sardines. It is also present in smaller amounts in certain plant-based sources like algae. The body can convert some alpha-linolenic acid (ALA), another omega-3 fatty acid found in flaxseeds and walnuts, into EPA, but this conversion is often inefficient.

Once consumed, EPA plays a role in various bodily functions. It is a component of cell membranes and is involved in the production of signaling molecules called eicosanoids, which regulate inflammation, blood clotting, and blood pressure. Research has explored the potential health benefits of EPA, particularly in relation to cardiovascular health, although scientific consensus on the extent of these benefits is ongoing. Supplementation with EPA, often in combination with docosahexaenoic acid (DHA), is a common practice for individuals seeking to increase their omega-3 intake.
