[Decanoic acid, new precursor for in vitro biosynthesis of oleic acid by a plant subcellular fraction].
Various membraneous fractions prepared from a cauliflower homogenate synthesize radioactive oleic acid when they are incubated in a 14C-decanolate solution. The more active fraction is formed of vesicles sedimenting at 30,000 g x 20 mn (heavy microsomes). The labelled precursor is transformed by this fraction mainly into oleic acid and hydroxyacids. ATP, NADPH, CoA and oxygen are required for these reactions. Labelled fatty acids, longer than lauric and (i.e. 14C-myristic, 14C-palmitic and 14C-stearic acids) are not transformed into oleic acid by the subcellular fraction studied in this paper.
