Study Notes
Metabolomics
- The study of the complete set of metabolites in an organism or cell.
- Explores the dynamic changes in metabolite concentrations in biofluids, cells, and tissues.
Origin of the term 'Metabolomics'
- Coined in the late 1990s, drawing inspiration from similar "-omics" fields like genomics and proteomics.
Metabolites
- Small molecules, such as sugars, amino acids, and fatty acids.
- Involved in metabolism, essential for cellular function, and reflect the state of an organism.
First Publication of 'Metabolomics'
- The word "metabolomics" first appeared in a 1998 publication by Oliver et al. in the journal "Metabolomics."
The Metabolome
- The complete set of metabolites present in a biological system at a specific point in time.
- Reflects the dynamic interactions between genes, proteins, and environmental factors.
