2. Participate in the metabolism of arachidonic acid. Produces prostaglandin compounds PGI3 and TXA3. The metabolites of arachidonic acid are prostacyclin (PGI2) and thromboxane (TXA2). PGI2 can relax blood vessels, prevent platelet aggregation and prevent thrombosis. TXA2 can cause vasospasm, promote platelet aggregation and thrombosis.
PGI3 has the same function as PGI2; But TXA3 does not have the function of TXA2. Therefore, EPA and DHA can dilate blood vessels, prevent platelet aggregation and prevent thrombosis.
3, anti-arrhythmia, reduce heart rate.
4. Lower blood pressure.
Can be used for treating hyperlipoproteinemia, atherosclerosis and coronary heart disease.
Extended data:
Omega-3 polyunsaturated fatty acids are fatty acids that cannot be synthesized by human body itself, and are also essential nutrients for human body to synthesize various hormones and endogenous substances. Only by supplementing these oleic acids with food can the physiological functions of the human body function normally.
Omega-3 fatty acids are eicosapentaenoic acid (EPA, containing 5 unsaturated bonds) and docosahexaenoic acid (DHA, containing 6 unsaturated bonds) from seals, fish and other substances, which contain more unsaturated bonds and have a strong role in regulating blood lipids.
It can promote the excretion of neutral or acidic cholesterol in feces, inhibit the synthesis of lipid and lipoprotein in liver, reduce cholesterol, triglyceride, low density lipoprotein (LDL) and very low density lipoprotein (VLDL) in plasma, and increase high density lipoprotein (HDL).
