Triglycerides containing acids with trans ‐3 unsaturation (16∶1 3 , 18∶1 3 and 18∶3 3, 9, 12 ) showed a marked retardation of reaction rate with pancreatic lipase. An inverse relationship was found between content of trans ‐3 unsaturated acids in seed oils and lipolysis rate. The trans ‐3 unsaturated acids were concentrated in the diglyceride and residual triglyceride fractions of the lipolysates, and only small amounts were present in the free acid and monoglyceride fractions.
