Polyunsaturated fatty acids are precursors to and are derived from polyunsaturated fats, which include drying oils.

While omega−3 polyunsaturated fatty acids may be beneficial in preventing heart disease in humans, the level of omega−6 polyunsaturated fatty acids (and, therefore, the ratio) does not matter. [33] [39] Both omega−6 and omega−3 fatty acids are essential: humans must consume them in their diet.
Intake of large doses (2.0 to 4.0 g/day) of long-chain omega−3 fatty acids as prescription drugs or dietary supplements are generally required to achieve significant (> 15%) lowering of triglycerides, and at those doses the effects can be significant (from 20% to 35% and even up to 45% in individuals with levels greater than 500 mg/dL).
Eicosapentaenoic acid (EPA) has 20 carbons, is found in fish oil, is a pentaunsaturated fatty acid. It is one of the essential fatty acids. The recommendation of ingesting fish oil supplements during pregnancy is said to help increase the cognitive ability at 6 months, but mercury concentration in fish products offsets the effect.
An appropriate balance of essential fatty acids—omega-3 and omega-6 fatty acids—seems also important for health, although definitive experimental demonstration has been elusive. Both of these "omega" long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the ...
16- and 18-carbon omega−7 unsaturated fatty acids are known to be converted into 18- or 20-carbon highly unsaturated fatty acids in the body by nonselective desaturating enzymes. [4] The same enzymes also act on omega−3, omega−6, and omega−9 fatty acids. As a result, while proportions of individual highly unsaturated fatty acids may ...
To illustrate the amounts of EPA and DHA in supplements, a softgel capsule containing fish oil derived from pollock might contain a total of 642 mg of total fish oil, of which 584 mg are omega−3 fatty acids, with 377 mg EPA and 158 mg DHA. 3 That same company's salmon oil softgel contains 1008 mg of total fish oil, of which 295 mg are omega ...
The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a polyunsaturated n−3 (omega-3) fatty acid. It is a regioisomer of gamma-linolenic acid (GLA), an 18:3 (n−6) fatty acid (i.e., a polyunsaturated omega-6 fatty acid with three double bonds).
