Inosine
From MyWiki
Inosine has been thought of in the B vitamin family, although it is not technically a vitamin because your body can synthesize it. It is a basic component of cells and participates in the synthesis of energy. Inosine is naturally formed as a result of purine metabolism. Purines fix nitrogen for use as basic building blocks of RNA and DNA. As inosine is formed it goes on to participate in the synthesis of ATP (cellular energy). Since inosine is readily formed as a byproduct of purine metabolism, we do not typically think of it as a needed dietary supplement. [ health news ]
