A New Mass Spectrometric Method for the Regiospecific Analysis of Triacylglycerols in Edible Oils and Fats
Edible fats and oils are mainly composed of complex mixtures of triacylglycerols (TAG). The position of fatty acid substitution on the glycerol backbone of a triacylglycerol (TAG) molecule is of considerable importance from a physiological1 and nutritional’ point of view. Consequently, in order to fully characterize a TAG molecule, it is necessary to know the constituent fatty acids and their position within the molecule. However, the ability to unambiguously identify positional isomers of individual TAGs, especially when they are components of complex natural mixtures, is a long standing problem in lipid chemistry.
