  • Title: Uptake and metabolism of fatty acids by soybean suspension cells.
    Author: Stumpf PK, Weber N.
    Journal: Lipids; 1977 Jan; 12(1):120-4. PubMed ID: 556796.
    Abstract:
    Soybean suspension cultures very rapidly take up C16 and C18 fatty acids by a nonspecific, nonenzymic binding of exogeneously added fatty acids to cell walls and by a subsequent transfer into the cell where they are rapidly incorporated into triacylglycerols, phosphatidylcholines, and phosphatidylethanolamines. 14C-Palmitic and 14C-stearic acids follow this sequence but are not desaturated, wherease 14C-oleic and 14C-linoleic acids are transferred more rapidly than the saturated fatty acids and are then further modified. All the data fit a sequence of events by which free oleic acid is first activated to a CoA thioester, and then desaturated to linoleyl-CoA; both thioesters are then transferred to triacylglycerols, phosphatidylcholine, and phosphatidylethanolamine.
