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

This analysis is used to determine the free fatty acid content of fats; i.e., the proportion of the triglycerides that have been hydrolyzed. Neutralization of fatty acids, like saponification , is a widely practiced route to metallic soaps .
An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond.
The evening primrose flower (O. biennis) produces an oil containing a high content of γ-linolenic acid, a type of omega−6 fatty acid.Omega−6 fatty acids (also referred to as ω−6 fatty acids or n−6 fatty acids) are a family of polyunsaturated fatty acids (PUFA) that share a final carbon-carbon double bond in the n−6 position, that is, the sixth bond, counting from the methyl end.
These days, "seed oil" is more of a pejorative term than a technical definition, referring to oils high in omega-6 fatty acid, including: Canola. Corn. Soybean. Cottonseed. Grapeseed. Sunflower ...
Omega−6 and omega−3 eighteen-carbon polyunsaturated fatty acids compete for the same metabolic enzymes, thus the omega−6:omega−3 ratio of ingested fatty acids has significant influence on the ratio and rate of production of eicosanoids, a group of hormones intimately involved in the body's inflammatory and homeostatic processes, which ...

The terms saturated vs unsaturated are often applied to the fatty acid constituents of fats. The triglycerides (fats) that comprise tallow are derived from the saturated stearic and monounsaturated oleic acids. [3] Many vegetable oils contain fatty acids with one (monounsaturated) or more (polyunsaturated) double bonds in them.
