"Arachidonic acid (AA), gamma linolenic acid (GLA) and linolenic acid
(LA) are three forms of Omega 6 fatty acids. Linoleic acid is
converted to gamma-linolenic acid in the body and then further broken
down to AA. Omega 6 fatty acid in the form of Arachidonic Acid can be
found in egg yolks, meats (organs in particular), and other animal
based food items. The other two forms GLA and LA can be found in
evening primrose oil, black currant seed oil, borage oil and fungal

"Omega-6 fatty acids are considered essential fatty acids (EFAs),
which means that they are essential to human health but cannot be made
in the body. For this reason, they must be obtained from food. Omega-3
fatty acids are another important group of essential fatty acids.
Together, omega-3 and omega-6 fatty acids play a crucial role in brain
function as well as normal growth and development. EFAs belong to the
class of fatty acids called polyunsaturated fatty acids (PUFAs). They
are generally necessary for stimulating skin and hair growth,
maintaining bone health, regulating metabolism, and maintaining
reproductive capability"

Definition for Arachidonic acid (AA):
"An unsaturated fatty acid, C20H32O2, found in animal fats, that is
essential in human nutrition and is a precursor in the biosynthesis of
some prostaglandins"

When you say "different egg yolks type" - do you mean for various
species of animals? Can you be more specific what are the animals you
need this information on?

Arachidonic acid is a carboxylic acid containing 20 carbon atoms
without any branching carbons.  In addition, it has 4 carbon-carbon
double bonds.  If the carboxylic carbon is numbered as C-1, then the 4
C=C double bonds are between C-5 and C-6, C-8 and C-9, C-11 and C12,
and C-14 and C-15, respectively.  All the 4 C=C double bonds have
