Arachidonic acid
Does anyone know a facile extraction (or synthesis) of arichidonic acid from natural sources? Supposedly it's only in animal fats. Is it in sufficient
amounts to make a synthesis worththe effort? Has anyone on this board ever tried this?

Its name suggests that arachidonic acid (which has 4 conjugated double bonds) might be in peanut oil (arachis species), along with arachic (less
unsaturated) and arachidic (saturated) acids, as the triglycerides. These are 20-carbon straight-chain acids. However, they would be only minor
constituents of peanut oil, which is mostly oleic acid (60%), linoleic acid (20%) (both 18-C unsaturated), stearic acid (5%) (18-C saturated),
palmitic acid (7%) (16-C saturated).

I looked it up, and unfortunately the names are only similar because they both have 20 carbon atoms, there is only a trace amount in peanut oil.

The building of long chain unsaturated fatty acids in the test tube is a pain. Best way often is isolation and selective culturing of some
microorganism, or gene splicing into a friendly bacteria.
