Biosynthesis of Conjugated Linoleic Acid ..

These figures showed three peaks at 215 nm, 232 and 270 nm representing respectively linoleic acid, rumenic acid and α-ESA. There were no conjugated s in rat tissues immediately before administration of the oil, but only the peak of linoleic acid appeared.
