Question

In nucleosides, both base and sugar are joined by:

• A. hydrogen bond
• B. $N$-glycoside bond
• C. $-S-S-$ bond
• D. both $A$ and $C$

Answer 1

Answer: (B)

$N$-glycoside bond

In nucleosides, both base and sugar are joined by $N$-glycoside bond. A nucleoside results from the linking of sugars (ribose or deoxyribose) with one of the purine or pyrimidine-derived bases through an $N$-glycosidic linkage.The chemical bond linking is then known as $N$- glycosidic bond.
