Une nouvelle voie de biosynthèse de l'acide oléique dans les végétaux

Oleic acid biosynthesis in Cauliflower slices has been studied from the following radioactive precursors: ¹⁴C-acetate, ¹⁴C-decanoate, ¹⁴C-laurate, ¹⁴C-palmitate, ¹⁴C-stearate and ¹⁴C-hydroxyacids derived from ¹⁴C-decanoate. The higher incorporation yield was obtained withe ¹⁴C-decanoate or the hydroxyacids derived from it. A new biosynthetic pathway for oleic acid, implying the intervention of a β-γ-hydroxylaurate-dehydrase is discussed.
