Triacylglycerol content of arachidonic acid varies inversely with total triacylglycerol in liver and plasma

In both liver and plasma from rats, hamsters, guinea pigs and monkeys, the correlation coefficients between percentage composition of arachidonic acid and the total triacylglycerol varied from -0.43 to -0.81 (P less than 0.01). No such relationship was present between percentage compositions of any of the essential fatty acids in phospholipids and total phospholipids.
