Fatty acids are mainly used in the production of soap, both for cosmetic purposes and, in the case of metallic soaps, as lubricants. Fatty acids are also converted, via their methyl esters, to fatty alcohols and fatty amines, which are precursors to surfactants, detergents, and lubricants. [17]

Essential fatty acids, or EFAs, are fatty acids that are required by humans and other animals for normal physiological function that cannot be synthesized in the body. [1] [2] As they are not synthesized in the body, the essential fatty acids – alpha-linolenic acid (ALA) and linoleic acid – must be obtained from food or from a dietary supplement.
In fatty acids the carbon atom of the methyl group at the end of the hydrocarbon chain is called the omega carbon because omega is the last letter of the Greek alphabet. Omega-3 fatty acids have a double bond three carbons away from the methyl carbon, whereas omega-6 fatty acids have a double

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.
Researchers found that certain omega−3 fatty acids are also converted into eicosanoids and docosanoids, [26] but at a slower rate. If both omega−3 and omega−6 fatty acids are present, they will "compete" to be transformed, [25] so the ratio of long-chain omega−3:omega−6 fatty acids directly affects the type of eicosanoids that are ...
In a lean young adult human, the mass of triglycerides stored represents about 10–20 kilograms. Triglycerides are formed from a backbone of glycerol with three fatty acids. Free fatty acids are activated into acyl-CoA and esterified to finally reach the triglyceride droplet. Lipoprotein lipase has an important role. [13]
