Metabolomics

Definition

Metabolomics is the scientific study of the chemical processes involving metabolites, which are small molecules produced during metabolism. This field focuses on the comprehensive analysis of metabolic profiles in biological samples, allowing for insights into biological pathways, disease states, and cellular responses. Through advanced techniques like mass spectrometry and chromatography, researchers can identify and quantify metabolites to better understand physiological and pathological processes.
