Metabolomics is the comprehensive study of metabolites, which are small molecules produced during metabolism. This field aims to analyze the chemical fingerprints left by cellular processes, providing insights into the physiological state of organisms. By examining these metabolites, researchers can better understand disease mechanisms, drug responses, and the effects of environmental changes on biological systems. The techniques used in metabolomics, such as mass spectrometry and nuclear magnetic resonance, allow scientists to identify and quantify metabolites in various biological samples. This information can lead to advancements in personalized medicine, agriculture, and environmental science, making metabolomics a vital area of research in modern biology.
