title: Defective desaturation and elongation of n-6 and n-3 fatty acids in hypertensive patients.
abstract: Hypertensive patients had higher levels of linoleic acid (LA) in serum lipids than normal controls. Administration of large doses of LA failed to raise the percentage of its metabolite arachidonic acid (AA) in serum lipids. Similarly, intake of large amounts of alpha-linolenic acid (alpha-LNA) failed to increase the amount of eicosapentaenoic acid (EPA). The percentage of EPA in serum lipids could readily be increased by direct administration of comparably low doses in a mackerel diet. Hypertensive subjects seem to desaturate and elongate LA and alpha-LNA only very slowly.
