[Incorporation of 1-C14 palmitic acid into liver lipids of rats in different hormanal states].

Abstract

Adrenalectomy and/or cortisol-induced variations in the in vivo and in vitro incorporation of 14C-palmitic acid 1 into the different fractions of rat liver lipids were studied. The different fatty acids incorporations follow analogous patterns in every hormonal state in vitro. Incorporation rate is faster in normal animals, but adrenalectomy or the administration of cortisol produces a marded delay. Cortisol does not modify the anomalism observed in the adrenoprival state. In vivo, the incorporation of palmitic acid into the different liver lipids--for the same hormonal state--does not follow the same pattern.
