MALDI Application: Structural Analysis of Oxidized Triolein

  • Summary

MSTips No. 197

In previous work, we showed that the JEOL SpiralTOF-TOF system’s high-energy collision-induced dissociation (HE-CID) is useful for the structural analysis of triglycerides.1 The resulting HE-CID mass spectra provided detailed information about the fatty acid moieties such as the positions of double bonds, branching, hydroxylation, and oxidation by means of charge-remote fragmentation (CRF).2 In this work, we report the structural analysis of oxidized triglycerides by HE-CID using the SpiralTOF-TOF
