Metabolome

Definition

The metabolome is the complete set of small-molecule chemicals found within a biological sample, such as a cell, tissue, or organism. It represents the end products of cellular processes and provides a snapshot of the physiological state at a given time.

5 Must Know Facts For Your Next Test

1. Metabolomics is the study of the metabolome using advanced analytical techniques like mass spectrometry and nuclear magnetic resonance.
2. The metabolome can be influenced by genetic factors, environmental conditions, and lifestyle choices.
3. Unlike genomics or proteomics, metabolomics reflects real-time changes in cellular processes and metabolic pathways.
4. Metabolomic profiling can be used to identify biomarkers for diseases, monitor therapeutic responses, and understand metabolic disorders.
5. Integration of metabolomic data with genomic and proteomic data enhances our understanding of complex biological systems.
