The fatty acid composition and glyceride distribution of fatty acids in pork, beef and lamb depot fats from different localities within the same animal were determined by a combination of gas liquid chromatography and lipase hydrolysis techniques. The glyceride distribution was calculated according to the method of Vander Wal, based on the 1, 3-random and 2-random distribution pattern. Both fatty acid composition and glyceride structure were found to vary depending on the position within the animal from which the depot fat was obtained.
