Vedclass · Answer

(D) non-reducing sugar is a carbohydrate that cannot be oxidized by a weak oxidizing agent like Tollens' reagent or Fehling's solution because it lacks a free hemiacetal or hemiketal group.$I$. Glucose is a reducing sugar due to the presence of a free aldehyde group.$II$. Fructose is a reducing sugar because it can isomerize to glucose/mannose in alkaline medium.$III$. Maltose is a reducing sugar as it contains a free hemiacetal group.$IV$. Sucrose is a non-reducing sugar because the glycosidic linkage is formed between the anomeric carbons of glucose and fructose,leaving no free hemiacetal or hemiketal group.$V$. Galactose is a reducing sugar due to the presence of a free aldehyde group.Therefore,only $IV$ (Sucrose) is a non-reducing sugar.

Which of the following are non-reducing sugars?
$I$. Glucose
$II$. Fructose
$III$. Maltose
$IV$. Sucrose
