Chiral analysis of lipids

WebA chiral lipidomics approach was established for comprehensive profiling of regio- and stereoisomeric monoepoxy and monohydroxy metabolites of long-chain PUFAs as generated enzymatically by cytochromes P450 (CYPs), lipoxygenases (LOXs), and cyclooxygenases (COXs) and, in part, also unspecific oxidations. The method relies on … WebCharged aerosol detection offers a new approach to the routine analysis of any nonvolatile lipid. It shows low ng (on column) sensitivity, a dynamic range of over four orders of magnitude, good reproducibility, gradient compatibility, and similar analyte response for nonvolatile species, independent of chemical structure.
