[1] [2] Some polyunsaturated fatty acids are essentials. Polyunsaturated fatty acids are precursors to and are derived from polyunsaturated fats, which include drying oils. [3] Chemical structure of the polyunsaturated fatty acid linoleic acid 3D representation of linoleic acid in a bent conformation Chemical structure of α-linolenic acid (ALA ...
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 ...

For fat in animals, see Adipose tissue. For chemistry of fats, see triglyceride. For other uses, see Fat (disambiguation). Idealized representation of a molecule of a typical triglyceride, the main ...
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]
Bacterial metabolism of soluble fibre also produces short-chain fatty acids like butyric acid which may be absorbed into intestinal cells as a source of food energy.

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.
Researchers found that certain omega−3 fatty acids are also converted into eicosanoids and docosanoids, [26] but at a slower rate. If both omega−3 and omega−6 fatty acids are present, they will "compete" to be transformed, [25] so the ratio of long-chain omega−3:omega−6 fatty acids directly affects the type of eicosanoids that are ...
