What is non-reducing sugar :

a) Maltose

b) Sucrose

c) Glucose

d) None of these

Reducing sugars are those that can donate electrons to another molecule because they have a free aldehyde or ketone group.
Examples: Glucose, Fructose, Maltose, Lactose.
Non-reducing sugars do not have a free aldehyde or ketone group because these groups are involved in a glycosidic bond, preventing them from acting as reducing agents.

🔹 Sucrose is a non-reducing sugar because it is formed by the condensation of glucose and fructose, where both the anomeric carbons (C1 of glucose and C2 of fructose) are involved in the glycosidic bond (α1→β2 linkage).
Hence, no free aldehyde or keto group remains to reduce other compounds like Benedict’s or Fehling’s reagent.
