Vedclass · Answer

(B) reducing sugar is a carbohydrate that can act as a reducing agent due to the presence of a free aldehyde or ketone group.All monosaccharides,such as $Ribose$ and $Fructose$,are reducing sugars.Among disaccharides,$Lactose$ is a reducing sugar because it contains a free hemiacetal group,whereas $Sucrose$ is a non-reducing sugar because its glycosidic linkage involves the anomeric carbons of both glucose and fructose units.Therefore,$II$ (Ribose),$III$ (Lactose),and $IV$ (Fructose) are reducing sugars.Hence,the correct option is $B$.

Which of the following are reducing sugars?
$I$. Sucrose
$II$. Ribose
$III$. Lactose
$IV$. Fructose
