Vedclass · Answer

(C) ribonucleoside consists of a ribose sugar molecule attached to a nitrogenous base. In a ribose sugar $(C_5H_{10}O_5)$,there are $-OH$ groups at the $C_2$,$C_3$,and $C_5$ positions. When the ribose sugar forms a nucleoside,the $-OH$ group at the $C_1$ position is replaced by the nitrogenous base. Therefore,the remaining $-OH$ groups are at the $C_2$,$C_3$,and $C_5$ positions. Thus,the total number of $-OH$ groups in a ribonucleoside is $3$.

What is the total number of $-OH$ groups present in a ribonucleoside?
