Uridine yog glycosylated pyrimidine-analog uas muaj uracil txuas rau lub nplhaib ribose (los yog ntau dua, aribofuranose) ntawm β-N1-glycosidic daim ntawv cog lus.Nws yog ib qho ntawm tsib tus qauv nucleosides uas tsim cov nucleic acids, lwm tus yog adenosine, thymidine, cytidine thiab guanosine.Lub tsib nucleosides feem ntau yog luv rau lawv ib tsab ntawv sau npe U, A, T, C thiab G feem.Txawm li cas los xij, thymidine feem ntau sau ua 'dT' ('d' sawv cev 'deoxy') raws li nws muaj 2'-deoxyribofuranose moiety ntau dua li lub nplhaib ribofuranose pom hauv uridine.Qhov no yog vim hais tias thymidine muaj nyob rau hauv deoxyribonucleic acid (DNA) thiab tsis ribonucleic acid (RNA).Hloov pauv, uridine muaj nyob hauv RNA thiab tsis yog DNA.Qhov seem peb nucleosides tuaj yeem pom hauv RNA thiab DNA.Hauv RNA, lawv yuav raug sawv cev ua A, C thiab G thaum hauv DNA lawv yuav sawv cev ua dA, dC thiab dG.
