Targeted lipidomics is a mass spectrometry-based approach designed to accurately detect and quantify selected lipid classes and lipid species with high sensitivity, specificity, and reproducibility.
For Caenorhabditis elegans, targeted lipidomics provides a robust way to reveal how genes, compounds, diets, environmental stressors, or disease-related interventions reshape lipid metabolism.
Lipids are essential biomolecules involved in membrane structure, energy storage, signal transduction, oxidative stress response, reproduction, development, and lifespan regulation. In C. elegans, lipid metabolism is closely associated with fat accumulation, stress resistance, aging, dauer formation, fertility, neurodegeneration, and metabolic disease-related responses.
Unlike untargeted lipidomics, which is mainly used for broad discovery, targeted lipidomics focuses on predefined lipid classes or lipid species. Multiple reaction monitoring, selected reaction monitoring, and optimized LC-MS/MS workflows enable reliable quantification across experimental groups.
Published studies have used targeted or quantitative lipidomics to evaluate active ingredients, nutrition-related interventions, aging phenotypes, and drug-related lipid pathway changes in C. elegans, supporting both academic mechanism studies and industrial product evaluation.
