      Summary

      Isolated rat aortas can incorporate acetate into various lipid classes when incubated in a suitable medium. The specific radioactivity of the free fatty acids is much higher than of the phospholipids, triglycerides and sterols. By far the lowest activity is found in the sterol ester fraction.

      Résumé

      Incubée dans un milieu approprié, l'aorte du rat isolée est capable d'incorporer l'acétate dans des classes diverses de lipides. La radioactivité spécifique des acides gras libres est beaucoup plus élevée que celle des phospholipides, des triglycérides et des stérines. L'activité bien la plus basse est retrouvée dans la fraction des stérines estérifiées.

      Zusammenfassung

      Die isolierte Aorta der Ratte kann Acetat in verschiedene Lipidgruppen einbauen wenn die Inkubation in einem geeigneten Medium stattfindet. Die spezifische Radioaktivität der freien Fettsäuren ist viel höher als die der Phospholipiden, Triglyzeriden und Sterine. In der Sterinester-Fraktion findet sich die weitaus geringste Aktivität.
