Summary
Lipidomics uses mass spectrometry to identify lipids and their roles in cell signaling and inflammation resolution. This approach helps understand complex lipid networks crucial for cell homeostasis and function.
Area of Science:
- Biochemistry
- Cell Biology
- Systems Biology
Background:
- Lipidomics decodes lipid information, identifying lipids and lipid-derived mediators.
- It is divided into architecture/membrane lipidomics and mediator lipidomics.
- Cell membranes, composed of lipids and proteins, are critical for cell function.
Purpose of the Study:
- To review lipidomic analyses using liquid chromatography tandem mass spectrometry.
- To explore bioactive lipid mediators in signaling pathways.
- To elucidate the role of lipid-derived mediators in inflammation resolution.
