Metabolomics

Definition

Metabolomics is the comprehensive study of metabolites, which are small molecules produced during metabolism, in biological samples. It aims to identify and quantify these metabolites to understand metabolic processes and their roles in health and disease. This field provides insights into the biochemical state of organisms and how various factors, like diet or environmental changes, can influence metabolism.
