[5' 13C]Uridine

[5' 13C]Uridine is a modified form of uridine, which is a nucleoside that is found in RNA. This modified form of uridine contains a stable isotope of carbon, 13C, at the 5' carbon position. This modification makes it an important tool for studying RNA structure and dynamics, as well as for metabolic tracing experiments. In terms of usage, [5' 13C]Uridine is often used in stable isotope labeling experiments, where it is incorporated into RNA molecules by cells or organisms. This allows researchers to track the fate of the labeled uridine and identify the RNA molecules that contain it. This can provide insights into RNA metabolism, RNA folding, and RNA-protein interactions. In addition to its usage in labeling experiments, [5' 13C]Uridine can also be used as a substrate for enzymes that modify RNA molecules. This allows researchers to study the effect of these modifications on RNA structure and function. From a chemical perspective, [5' 13C]Uridine is a modified nucleoside that is structurally similar to the natural uridine molecule. It contains a ribose sugar, a uracil base, and a 13C atom at the 5' carbon position. The modification does not significantly alter the chemical properties of the molecule, but it does make it useful for specific research applications.
