The Principle of Combining Lipidomics and Metabolomics
The principle of combining lipidomics and metabolomics involves comprehensively analyzing the dynamic changes of lipid molecules and metabolites to reveal the complex metabolic networks in biological systems. This approach captures the complete profile of lipids and metabolites within cells through high-resolution mass spectrometry and liquid chromatography technologies, effectively identifying and quantifying a large number of compounds. By integrating these two omics methods, researchers can gain deep insights into the interactions between lipid metabolism and overall metabolic pathways, uncovering their changes in physiological and pathological states.
Applying the principles of combining lipidomics and metabolomics helps identify potential biomarkers and provides new insights into disease mechanisms. This combined approach can precisely trace key nodes in metabolic pathways, assessing how interactions between metabolites and lipid molecules affect cell function and disease progression.
