In silico-predicted characteristic fragment ions database (CFID) for in-depth regiospecific analysis of triacylglycerol regioisomers based on UPLC-EIEIO-MS/MS.

The regiospecific analysis of triacylglycerols (TGs) remains a critical challenge due to their structural complexity, particularly in distinguishing regioisomers like AAB/ABA and ABC/ACB types. In this study, a novel strategy combining electron impac…
