Vedclass · Answer

(C) sugar is non-reducing if its anomeric carbon atoms are involved in the glycosidic linkage,meaning no free hemiacetal or hemiketal group is available to open into an aldehyde or ketone form.$(i)$ Represents Maltose,which has a free anomeric carbon and is a reducing sugar.(ii) Represents Lactose,which has a free anomeric carbon and is a reducing sugar.(iii) Represents Sucrose,where both anomeric carbons ($C1$ of glucose and $C2$ of fructose) are involved in the glycosidic linkage,making it a non-reducing sugar.(iv) Represents Cellobiose,which has a free anomeric carbon and is a reducing sugar.Therefore,only structure $(iii)$ is a non-reducing sugar.
