Patterns of Urinary Excretion of Modified Nucleosides1


malian cells; consequently, the nucleosides are excreted (2). An example of this fail-safe system is the level of excretion of uridine and pseudouridine; the former, which is a major component of RNA, is excreted in traces only since it can be recycled into the macromolecule, but the latter, which is a minor component of RNA, is voided in quantities as… (More)
