Isotopomeranalysen, also known as isotopomer analysis, is a technique used in the field of analytical chemistry to study the distribution of isotopes within molecules. This method is particularly valuable in metabolic studies, as it allows researchers to trace the flow of carbon atoms through biological systems. By using isotopically labeled compounds, scientists can track the incorporation of these labels into endogenous molecules, providing insights into metabolic pathways and enzyme activities.

The technique involves the use of mass spectrometry to measure the abundance of different isotopomers, which are molecules with the same molecular formula but different arrangements of isotopes. Isotopomer analysis can be applied to a wide range of biological samples, including tissues, cells, and biofluids. It is commonly used in studies of carbon metabolism, nitrogen metabolism, and sulfur metabolism, among others.

One of the key advantages of isotopomer analysis is its ability to provide detailed information about the kinetics of metabolic processes. By monitoring the changes in isotopomer distribution over time, researchers can determine the rates of enzyme-catalyzed reactions and the turnover of metabolic intermediates. This information is crucial for understanding the regulation of metabolic pathways and the response of biological systems to various stimuli.

Isotopomer analysis has been instrumental in advancing our understanding of metabolism and has applications in fields such as nutrition, pharmacology, and toxicology. It has also contributed to the development of metabolic models and the identification of biomarkers for disease diagnosis and monitoring. As analytical techniques continue to evolve, isotopomer analysis is expected to play an increasingly important role in metabolic research.
