In biochemistry and nutrition, a polyunsaturated fat is a fat that contains a polyunsaturated fatty acid (abbreviated PUFA), which is a subclass of fatty acid characterized by a backbone with two or more carbon–carbon double bonds. [1] [2] Some polyunsaturated fatty acids are essentials.

Oleic acid has 18 carbons, is found in most animal fats and olive oil, and is a cis-9-monounsaturated fatty acid. C 17 H 33 CO 2 H, IUPAC organization name (Z)-octadec-9-enoic acid, numerical representation 18:1 (9), n-9, molecular weight 282.46, melting point 13.4 °C, specific gravity 0.891. CAS Registry Number 112-80-1.
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.

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 ...

For example, α-linolenic acid (ALA; illustration) is an 18-carbon chain having three double bonds, the first located at the third carbon from the methyl end of the fatty acid chain. Hence, it is an omega−3 fatty acid. Counting from the other end of the chain, that is the carboxyl end, the three double bonds are located at carbons 9, 12, and 15.
