Xanthosine
Xanthosine is a nucleoside found in humans and other organisms. It is composed of a hypoxanthine base attached to a ribose sugar. Xanthosine is a precursor to guanosine, a key component of RNA and DNA. It is involved in purine metabolism, the biochemical process that synthesizes and breaks down purines, which are essential building blocks of nucleic acids.
In the body, xanthosine is primarily synthesized in the liver. It plays a role in the salvage
Research has explored the potential roles of xanthosine beyond its role in purine metabolism. Some studies
