I-Uridine iyi-glycosylated pyrimidine-analog equkethe i-uracil enamathiselwe kwendandatho ye-ribose (noma ikakhulukazi, i-aribofuranose) nge-β-N1-glycosidic bond.Ingenye yama-nucleoside amahlanu ajwayelekile akha ama-nucleic acid, amanye kube i-adenosine, i-thymidine, i-cytidine ne-guanosine.Ama-nucleoside amahlanu avamise ukufushaniswa kumakhodi awo anohlamvu olulodwa u-U, A, T, C kanye no-G ngokulandelana.Nokho, i-thymidine ivame ukubhalwa ngokuthi 'dT' ('d' imele 'deoxy') njengoba iqukethe i-2'-deoxyribofuranose moiety kuneringi ye-ribofuranose etholakala ku-uridine.Lokhu kungenxa yokuthi i-thymidine itholakala ku-deoxyribonucleic acid (DNA) hhayi i-ribonucleic acid (RNA).Ngokuphambene, i-uridine itholakala ku-RNA hhayi ku-DNA.Ama-nucleoside amathathu asele angatholakala kukho kokubili i-RNA ne-DNA.Ku-RNA, bazomelwa njengo-A, C no-G kuyilapho ku-DNA bezomelwa njenge-dA, dC kanye ne-dG.
