Structure analysis of triacylglycerol positional isomers using atmospheric pressure chemical ionisation mass spectrometry

Abstract

Fragmentation of triacylglycerols by atmospheric pressure ionisation allows identification of positional isomers. The relative intensities of the [M-RCO 2] + ions provide information on the position of fatty acids within an ABC type triacylglycerol and enable ABA and AAB type molecules to be distinguished.
