Summary

Metabolite profiling quantifies mixtures of compounds using chromatography and mass spectrometry (GC-MS, LC-MS). This study details GC-MS strategies for profiling polar compounds, covering essential experimental steps.

Area of Science:

  • Biochemistry
  • Analytical Chemistry

Background:

  • Metabolite profiling offers a broad overview of biochemical events, extending classical single-target methods.
  • It involves multiparallel relative quantification of compound mixtures using chromatography and universal detection (GC-MS, LC-MS).
  • While offering a wider scope, it may involve compromises in method development and reduced accuracy for specific metabolites.

Purpose of the Study:

  • To exemplify strategies for metabolite profiling of polar compounds using gas chromatography-mass spectrometry (GC-MS).

Main Methods:

  • Detailed experimental steps for GC-MS metabolite profiling are provided.
  • These include sample harvest, homogenization, extraction, fractionation, concentration, and derivatization.
  • Data acquisition, raw data processing, and result data transformation are also covered.
