Essential+Fatty+acid

Only two EFAs are known for humans: [|alpha-linolenic acid] (an [|omega-3 fatty acid]) and [|linoleic acid] (an [|omega-6 fatty acid]).[|[2]][|[3]][|[4]] Other fatty acids that are only "conditionally essential" include [|gamma-linolenic acid] (an omega-6 fatty acid), [|lauric acid] (a saturated fatty acid), and [|palmitoleic acid] (a monounsaturated fatty acid).[|[5]] When the two EFAs were first discovered in 1923, they were designated **Vitamin F**. In 1930, work by Burr, Burr and Miller on rats showed that the two EFAs are better classified with the [|fats] than with the [|vitamins].[|[6]]
 * Essential fatty acids**, or **EFAs**, are [|fatty acids] that humans and other animals must ingest because the body requires them for good health but cannot [|synthesize] them.[|[1]] The term "essential fatty acid" refers to fatty acids required for biological processes, and not those that only act as fuel.
