"Uridine or deoxythymidyne are neucleosides formed when nitrogen base is linked to the pentosugar through a N-Glycosidic linkage" ..,, is it true ? please explain? |
Nucleosides are formed by joining a Nitrogenous Base to a Ribose Sugar. A ribose and nitrogenous base are covalently joined by a glycosidic bond to form a nucleoside molecule. Glycosidic bonds in nucleosides are always b-type glycosidic bonds. Nucleosides are named by adding the suffix "-idine" to the pyrimidine or "-osine" to the purine name. Pyrimidine nucelosides include Cytidine, Thymidine, and Uridine Purine nucleosides include Adenosine and Guanosine. |
