Environmental Metabolomics

Definition

Environmental metabolomics is the comprehensive study of small molecules, known as metabolites, in environmental samples and biological systems to understand how organisms respond to environmental changes or stressors. This approach allows researchers to analyze the dynamic interactions between organisms and their environments, linking biochemical pathways with ecological outcomes and aiding in the assessment of ecosystem health.
