Metabolomics

Definition

Metabolomics is the comprehensive study of small molecules, or metabolites, within biological systems, providing insights into metabolic processes and cellular responses. By analyzing the entire set of metabolites present in a cell, tissue, or organism, researchers can gain a better understanding of biological functions and disease mechanisms. This field integrates with bioinformatics and computational biology to handle the large datasets generated from metabolomic analyses, making it crucial for uncovering complex metabolic pathways and their regulation.
