Abstract

Fifteen triacylglycerols containing 12∶0, 14∶0, 16∶0, 18∶2 and one positional isomer ofcis-18∶1 were hydrolyzed by pancreatic lipase (EC 3.1.1.3, glycerol ester hydrolase). The fatty acids in the products of lipolysis were identified and measured by gas liquid chromatography. The substrates containing the Δ2 through Δ7 isomers of 18∶1 were resistant to pancreatic lipolysis. These isomers accumulated in the di- and residual triacylglycerols and were diminished in the free fatty acids. The discrimination was greates against the Δ5 isomer.
