Metabolomics

Definition

Metabolomics is the comprehensive study of metabolites, the small molecules produced during metabolism, within a biological sample. This field helps in understanding cellular processes and physiological states by providing insights into the biochemical changes associated with different conditions or treatments. It is vital for integrating with other omics technologies, facilitating a holistic view of biological systems, and aiding in applications ranging from drug discovery to understanding disease mechanisms.
