Comparison between 1H-NMR and LC-MS methods for determining ratios of phospholipid concentrations in livers from mice fed different diets in the dietary study.
| Concentration Ratio | PE | PC + LPC | SM | Total PL, Except LPC | ||||
|---|---|---|---|---|---|---|---|---|
| LC-MS | NMR | LC-MS | NMR | LC-MS | NMR | LC-MS | NMR | |
| COCO/REF | 0.94 | 0.95 | 1.07 | 1.01 | 0.90 | 0.81 | 1.05 | 1.03 |
| FISH/REF | 1.24 | 1.17 | 1.13 | 1.06 | 1.00 | 1.10 | 1.12 | 1.08 |
Abbreviations: COCO, a diet with 5% saturated FA-rich oil; REF: a diet with 5% reference oil (control); FISH: a diet with 5% n-3 long-chain PUFA-rich oil; PE, phosphatidylethanolamine; PC, phosphatidylcholine; LPC, lysophosphatidylcholine; PL, phospholipids;.
