The structural components of milk triglycerides

Abstract
Pancreatic lipase hydrolysis and gas chromatographic analysis of two samples of butter fat show that the individual acyl groups are not dispersed at random among all the glyceryl carbons. When considered only as saturated or unsaturated, and not as individuals, they appear to be distributed intermolecularly at random, or nearly so, but tend to assume specific positions intramolecularly.
