Stress Metabolomics

Definition

Stress metabolomics is the study of metabolites and metabolic pathways in organisms experiencing environmental or physiological stress. It focuses on understanding how stress affects cellular metabolism, revealing biomarkers that can indicate stress responses and adaptations in organisms. This field is crucial for understanding ecological interactions, organismal health, and responses to climate change or pollution.
