Metabolomics

Definition

Metabolomics is the comprehensive study of metabolites, the small molecules produced during metabolism, within a biological system. This field allows scientists to understand cellular processes and interactions by profiling metabolic changes in response to various conditions. It is closely connected to various analytical techniques that help identify and quantify these metabolites, offering insights into biological functions and disease mechanisms.
