“The metabolism of linoleic acid seems to be disturbed with increased proportions of dihomo-gamma linolenic acid (20 : 3 n-6) and a reduced activity of the Δ5 desaturase, while the activities of the Δ9 and Δ6 desaturases appear to be increased.”
“The ratio linoleic acid/dihomo-gamma-linolenic acid , reflecting the delta 6-desaturation and the following elongation step, increased with rising linoleic acid values.”

“A diet providing a large amount of linoleic acid (14% of the total caloric intake) resulted in low levels of dihomo-gamma-linolenic acid (C20:3 omega 6) and arachidonic acid (C20:4 omega 6) in serum phospholipids and cholesteryl esters.”
“Stearic acid, a long-chain saturate, does not produce any reduction, whereas eicosatrienoic acid is an even more effective inhibitor than linoleic acid.”

“The conversion of linoleic into γ-linolenic acid and eicosatrienoic into arachidonic acid were mutually inhibited and the inhibition depended on the concentration of the fatty acids incubated.”
“However, the desaturation of eicosa-8,11,14-trienoic acid is strongly enhanced by linoleic and γ-linolenic acids which may account for its non-accumulation in tissue lipids.”
“The conversion of linoleic into 3' -linolenic acid and eicosatrienoic i n t o arachidonic acid were mutually inhibited and the inhibi t ion depended on the concentration of the fatty acids incubated.”
“Supplementation of the essential fatty acid-deficient diet with linoleic acid caused a rapid loss of eicosatrienoic acid and palmitic acid with a concomitant increase in stearic acid and arachidonic acid.”
