Translations:Fatty acid/23/en

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 of multiple double bonds such as the essential fatty acids. Thus linoleic acid (18 carbons, Δ^9,12), γ-linolenic acid (18-carbon, Δ^6,9,12), and arachidonic acid (20-carbon, Δ^5,8,11,14) are all classified as "ω−6" fatty acids; meaning that their formula ends with –CH=CH–CH
