Abstract
SUMMARY— Samples of triglycerides and triglyceride mixtures were heated in the presence of water under controlled conditions and the released fatty acids quantitatively analyzed by gas chromatography. Experiments with both a mixture of monoacyl‐triglycerides and glycerides with equimolar amounts of randomly distributed fatty acids showed a preference for the hydrolysis of the shorter chain and the unsaturated fatty acids. The C4, C8, C12, and C18:1, fatty acids were used in the above mixtures. A trilaurin, in which the fatty acid in the P‐position is labelled with C14, was synthesized. When the free acids released by heat were analyzed by a combination gas chromatographic‐radioactivity detector system, no evidence for a positional specificity was apparent.
