Molecular Species of Phosphatidylcholine in Plants: Biosynthesis and Role in Oleate Desaturation or Freezing Resistance
High performance liquid chromatography has recently offered the possibility to separate all the molecular species (differing by their component fatty acids) forming a peculiar lipid class in a plant tissue. Thus a real molecular biology of lipids is now on progress in several laboratories1,3. The purpose of this paper is to present some recent data obtained in our laboratory, concerning the biosynthesis of various phosphatidylcholine molecular species on one side and the role played by these molecules in oleate desaturation or freezing-resistance, on the other side.
