I thought it was only oleic, linoleic and linolenic acid but I've read also arachidonic! Do you know the answer?

yes u r right arachidonic acid is an essential acid

But it can be produce in the organism by PLA2. So it shouldn't be essential. I'm lost!!!:crazy:

ω-6 fatty acids (http://en.wikipedia.org/wiki/Omega-6_fatty_acid):

linoleic acid (http://en.wikipedia.org/wiki/Linoleic_acid) or LA (18:2)
gamma-linolenic acid (http://en.wikipedia.org/wiki/Gamma-linolenic_acid) or GLA (18:3)
dihomo-gamma-linolenic acid (http://en.wikipedia.org/wiki/Dihomo-gamma-linolenic_acid) or DGLA (20:3)
arachidonic acid (http://en.wikipedia.org/wiki/Arachidonic_acid) or AA (20:4)
these are essential in humans
some orgs can produce but not humans

The essential fatty acids are:
Alpha-Linolenic acid (http://en.wikipedia.org/wiki/Alpha-linolenic_acid) (18:3) - ω-3
Linoleic acid (http://en.wikipedia.org/wiki/Linoleic_acid) (18:2) - ω-6ω-9 fatty acids (http://en.wikipedia.org/wiki/Omega-9_fatty_acid) are not essential in humans, because humans possess all the enzymes required for their synthesis. oleic is not essential.

arachidonic can be synthesized from linoleic. mnenonic linolEIc-Arachidonic. A [EI]
