The reason for the susceptibility of nucleosides to acidic hydrolysis and the mechanism of this hydrolysis is to be explained. Concept introduction: 舧 Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair. 舧 Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair. 舧 A nucleoside consists of a nucleobase (also termed as nitrogenous base) and a five-carbon sugar (either ribose or deoxyribose). 舧 A nucleotide consists of a nucleobase (also termed as nitrogenous base), a five-carbon sugar (either ribose or deoxyribose) and one or more phosphate groups. 舧 In a nucleoside, the anomeric carbon is linked through a glycosidic bond to the N9 of a purine or N1 of a pyrimidine. 舧 Examples of nucleosides include cytidine, uridine, adenosine, guanosine and thymidine. 舧 Sugar (ribose/deoxyribose) and nitrogenous bases are linked through N-glycosidic bonds. 舧 These glycosidic bonds are formed by condensation reaction of first carbon of sugar molecule with the nitrogen atom ( N1 of pyrimidines and N9 of purines) of the nitrogenous base. 舧 This particular glycosidic bond is stable in basic solutions, but readily hydrolyzes in the presence of acids.
