| Outline of Final Research Achievements |
We applied supercritical fluid chromatography (SFC) to the enantiomeric separation of lipids and tried to construct the chiral lipidomics system. We successfully separated triacylglycerol (TAG) enantiomeric isomers with connected chiral columns. Additionally, SFC also allows us to separate TAG positional isomers. Furthermore, we performed the analyses of biologicalsamples by using the constructed chiral lipidomics system. We achieved the enantiomeric separation of TAG enantiomeric isomers and positional isomers in edible oils. Additionally, we performed the chiral lipidomics in diabetes and myocardial infarction samples and obtained specific profiles.
