Products include fatty acid hydroperoxides, epoxy-hydroxy polyunsaturated fatty acids, jasmonates, divinylether fatty acids, and leaf aldehydes. Some of these derivatives are signalling molecules, some are used in plant defense ( antifeedants ), some are precursors to other metabolites that are used by the plant.
Cervonic acid (or docosahexaenoic acid) has 22 carbons, is found in fish oil, is a 4,7,10,13,16,19-hexa unsaturated fatty acid. In the human body its generation depends on consumption of omega 3 essential fatty acids (e.g., ALA or EPA), but the conversion process is inefficient. [22]
Lists of fatty acids include: List of saturated fatty acids; List of unsaturated fatty acids. List of omega-3 fatty acids, a class of unsaturated fatty acids; See also
Omega−3 fatty acids are important for normal metabolism. [ 2 ] Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from ...
Saturated fatty acids 16 and 18 carbons in length are the dominant types in the epidermis, [39] [40] while unsaturated fatty acids and saturated fatty acids of various other lengths are also present. [ 39 ] [ 40 ] The relative abundance of the different fatty acids in the epidermis is dependent on the body site the skin is covering. [ 40 ]
There are a number of polyunsaturated fatty acids that can be reinforced by deuteration. [2] They include (the names of the reinforced deuterated versions are separated by a slash): linoleic acid / D 2-linoleic acid (D2-Lin) α-linolenic acid / D 4-α-linolenic acid (D4-Lnn) arachidonic acid / D 6-arachidonic acid (D6-ARA)
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.
While omega−3 polyunsaturated fatty acids may be beneficial in preventing heart disease in humans, the level of omega−6 polyunsaturated fatty acids (and, therefore, the ratio) does not matter. [33] [39] Both omega−6 and omega−3 fatty acids are essential: humans must consume them in their diet.
