Analysis of arachidonic-acid-containing molecular species in glycerophospholipid classes from rat kidney by fast-atom bombardment mass spectrometry

Abstract
The qualitative analysis of the molecular species of phosphatidylinositol, phosphatidylethanolamine, phosphatidylcholine and phosphatidylserine from a rat kidney, by fast‐atom bombardment mass spectrometry after separation and purification by liquid chromatography is described. The present results indicate that a high content of arachidonic‐acid‐containing molecular species within major glycerophospholipid classes is present in this biological sample.
