Metabolomics is the comprehensive study of small molecules, known as metabolites, within cells, tissues, or organisms. These metabolites are the end products of cellular processes, reflecting the underlying biochemical activity and state of a biological system. By analysing the complete set of metabolites, metabolomics provides a snapshot of the metabolic state, which can be influenced by genetics, environment, diet, and disease. This field utilises advanced analytical technologies such as nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), and chromatography to identify and quantify these metabolites. Metabolomics is crucial in biomarker discovery, understanding disease mechanisms, personalized medicine, and evaluating the effects of interventions like drugs or diet on metabolic pathways.
