This study presents practical guidelines and methods for measuring oxylipins, including jasmonates and hydroxy-fatty acids. These techniques, utilizing gas chromatography/mass spectrometry, are accessible for researchers studying lipid oxidation and cellular signaling.

Area of Science:

  • Lipidomics
  • Analytical Chemistry
  • Biochemistry

Background:

  • Oxylipins are crucial signaling molecules involved in various biological processes.
  • Accurate measurement of oxylipins is essential for understanding their roles in health and disease.
  • Existing methods may require specialized expertise or advanced instrumentation.

Purpose of the Study:

  • To provide practical guidelines for monitoring and measuring diverse oxylipins.
  • To describe a protocol for analyzing non-enzymatic lipid oxidation.
  • To offer accessible methods for oxylipin quantification and internal standard preparation.

Main Methods:

  • Gas chromatography/mass spectrometry (GC/MS) based methods.
  • Protocols for analyzing jasmonates, ketols, ketodi(tri)enes, and hydroxy-fatty acids.
