A method for determining regioisomer abundances of polyunsaturated triacylglycerols in omega-3 enriched fish oils using reversed-phase liquid chromatography and triple-stage mass spectrometry

► A method for quantifying regioisomers of triacylglycerols in fish oil is reported. ► Liquid chromatography coupled to triple-stage mass spectrometry was employed. ► Triacylglycerols containing the beneficial fatty acids EPA and DHA were measured. ► DHA was preferentially located at the sn-2 positi...
