Examples of n-6 fatty acids are: linoleic and arachidonic acid. There is also a common pattern in the location of double bonds; in most monounsaturated fatty acids the double bond is between C-9 and C-10 (9), and the other double bonds of polyunsaturated fatty acids are generally 12 and 15. ChEBI CHEBI:15843: A long-chain fatty acid that is a C20, polyunsaturated fatty acid having four (Z)-double bonds at positions 5, 8, 11 and 14. Fatty acids. number of carbon-t, Unlike saturated fats, the fatty acid tails of unsaturated fats incorporate , True/FalseFatty acids having no double bonds are called "unsaturate, Determine whether or not each molecule is a fatty acid. Arachidonic acid, which is found in meat, eggs, and some fish, is a polyunsaturated fat with 20 carbons and 4 double bonds, so it is described in shorthand notation as (20:4). However, substitution of Ile-ll4 with Ala, resulted in a significant reduction in the degree of epoxidation at the 14,15- and 11,12-double bonds, and the 8,9- and 5,6-EETs were the major products. Using this method, arachidonic acid has a double bone at the 6th position from the carboxyl group. While certain saturated and trans fats continue to face scrutiny as health hazards, new evidence indicates that, in addition to supplying foods with flavor and texture, fats also provide us with dietary components that are absolutely Chemical Structure of Arachidonic Acid (NLM, 2011b) 35 Arachidonic acid single-cell oil (ARA Single-cell Oil) is a triglyceride oil extracted from a soil fungus and 36 enriched with a commercial grade high oleic sunflower oil to approximately 40% ARA by weight (Hogan & 37 Hartson L.L.P., 2000; Wyeth-Ayerst, 1998; EFSA, 2008).

The synthesis of prostaglandins in our bodies starts with arachidonic acid (see figure below), a long, unsaturated hydrocarbon containing four C=C double bonds and an acid functional group (-COOH). I hope the enformation contained in this book helps the reader to understand that, not all fats are detremental. Moreover, this book informs its readers that fats are just as important as the other classes of nutrients. The series 2 prostaglandins are derived from arachidonic acid and series 3 prostaglandins are synthesized from EPA. 12. Arachidonic acid is a 20-carbon omega6 fatty acid with 4 double-bonds.

Cats require AA due to the lack of delta-6 desaturase, . 5-HPETE is an intermediate in the biological conversion of arachidonic acid to leukotrienes, potent molecules that contribute to the asthmatic response (Section 9.16). Arachidonic Acid Metabolism. Thromboxanes and prostaglandins both contain a carboxyl group. Unsaturated fatty acids possess one or more double bonds in their carbon chains. The action of enoyl CoA isomerase is required to handle double bonds at odd-numbered carbons because beta-oxidation generates or requires pre-existing double bonds at even-numbered carbons. 1.
