Metabolomics

Definition

Metabolomics is the comprehensive study of metabolites, which are the small molecules produced during metabolism in biological systems. This field aims to analyze the complete set of metabolites in a biological sample to understand the underlying biochemical processes and how they interact with proteins, genes, and other cellular components.

5 Must Know Facts For Your Next Test
