Which statements about reducing sugars are true? D‑Glucose (an aldose) is a reducing sugar. The oxidation of a reducing sugar forms a carboxylic acid sugar. A disaccharide with its anomeric carbons joined by the glycosidic linkage cannot be a reducing sugar. Reducing sugars contain ketone groups instead of aldehyde groups. A reducing sugar will not react with the Cu2+ in Benedict's reagent.

Answer:

The true statements are given below.

Explanation:

1 D glucose is a reducing sugar

2 The oxidation of reducing sugar forms a carboxylic acid sugar.

D glucose is a reducing sugar because glucose contain a free hydroxyl group (-OH)in its anomeric carbon.

 The oxidation of reducing sugar result in the conversion of -CHO group in case of aldose sugar and -CH2OH group in case of ketose sugar into carboxylic acid(-COOH).
