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

Omega-3 fatty acids, also called ω−3 fatty acids or n−3 fatty acids, [1] are polyunsaturated fatty acids (PUFAs). Omega−3 fatty acids are important for normal metabolism.
The IUPAC Lipid Handbook provides a very large and detailed listing of fat contents of animal and vegetable fats, including ω−3 and −6 oils. [25] The National Institutes of Health's EFA Education group publishes Essential Fats in Food Oils. [26] This lists 40 common oils, more tightly focused on EFAs and sorted by n−6:3 ratio.
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.
For example, a recent large meta-analysis found that replacing some saturated fats with polyunsaturated fats (like seed oils) was associated with a lower reduced risk of cardiovascular disease and ...
Mackenzie Burgess, a registered dietitian and recipe developer at Cheerful Choices, tells Yahoo Life that omega-6 fats are typically found in high amounts in less healthful sources of foods that ...
The foods that account for the biggest sources of saturated fats in Americans’ diets include cheese, pizza, ice cream and eggs. “Whether it’s omega-6 or omega-3 is fairly trivial,” Gardner ...
Thus, for example, the 20-carbon arachidonic acid is Δ 5,8,11,14, meaning that it has double bonds between carbons 5 and 6, 8 and 9, 11 and 12, and 14 and 15. In the context of human diet and fat metabolism, unsaturated fatty acids are often classified by the position of the double bond closest between to the ω carbon (only), even in the case ...
