[1',2',3',4',5'-13C5]inosine

[1',2',3',4',5'-13C5]inosine is a labeled form of inosine, which is a nucleoside that is made up of a purine base and a ribose sugar. This labeled form of inosine contains five stable carbon-13 isotopes in the 1', 2', 3', 4', and 5' positions of the ribose sugar. This labeling is useful in a variety of applications including metabolic labeling, metabolic flux analysis, and nuclear magnetic resonance (NMR) spectroscopy. Metabolic labeling is a technique used to track the movement of molecules in a metabolic pathway. By using a labeled molecule, such as [1',2',3',4',5'-13C5]inosine, researchers can follow the carbon atoms through different chemical reactions and determine which metabolites are produced. This technique is particularly useful in studying metabolic disorders and drug metabolism. Metabolic flux analysis is another technique that utilizes labeled molecules. By measuring the isotopic enrichment of different metabolites, researchers can calculate the rate of flux through different pathways of metabolism. This technique can be used to study the effects of genetic mutations, environmental factors, and drug treatments on metabolic pathways. Finally, NMR spectroscopy is a powerful tool for studying the structure and dynamics of molecules. The incorporation of carbon-13 isotopes into inosine allows researchers to obtain more detailed information about the molecule's conformation and interactions with other molecules. In conclusion, [1',2',3',4',5'-13C5]inosine is a valuable tool for researchers studying metabolism and molecular interactions. Its stable isotope labeling allows for precise tracking of carbon atoms in metabolic pathways, and its use in NMR spectroscopy provides detailed information about molecular structure and dynamics.
