37 Facts About Metabolomics

What is Metabolomics?

Metabolomics is the large-scale study of small molecules, commonly known as metabolites, within cells, biofluids, tissues, or organisms. These molecules and their interactions provide a snapshot of the physiological state of a cell or organism. Let's dive into some fascinating facts about this intriguing field.

1. Metabolomics focuses on the chemical processes involving metabolites, which are the end products of cellular processes.
2. The field emerged in the late 1990s, making it a relatively new area of study compared to genomics and proteomics.
3. Metabolomics can provide a direct functional readout of the physiological state of an organism, unlike genomics which only provides potential information.

Techniques Used in Metabolomics

Various sophisticated techniques are employed to analyze metabolites. These methods help scientists understand the complex biochemical processes in living organisms.

4. Mass spectrometry (MS) is one of the primary techniques used in metabolomics for identifying and quantifying metabolites.
5. Nuclear magnetic resonance (NMR) spectroscopy is another powerful tool used to study the structure and dynamics of metabolites.
6. Liquid chromatography-mass spectrometry (LC-MS) combines the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry.
7. Gas chromatography-mass spectrometry (GC-MS) is used for analyzing volatile compounds and is highly sensitive.
8. Capillary electrophoresis-mass spectrometry (CE-MS) is used for separating ionic species by their charge and size.
