The Impact of the Complexing Agent on the Sensitivity of Collisional-Induced Dissociation Spectra to Fatty Acid Position for a Set of XYZ-Type Triglycerides.

The data shows that that the relative abundances of the DAG product ions for the XYZ-type TAGs when using sodium and lithium complexing agents adducts are sensitive to fatty acid position and are consistent for the diverse array of TAGs studied in this work. This suggests that using sodium or lithium as the complexing agent may be advantageous for the development of an automated platform for the positional analysis of complex TAG mixtures based on ESI-MS/MS.
