when [ 1-14c ] linoleic acid was incubated with control ( 480 microm mg2+ ) or magnesium deficient cells ( 2.6 microm mg2+ ) the rate of tetraenoic acid synthesis ( 20:4 ( n-6 ) + 22:4 ( n-6 ) was significantly reduced in magnesium-deficient cells , indicating that the metabolic conversion of 18:2 ( n-6 ) to 20:4 ( n-6 ) is impaired in magnesium deficiency .
