Sucrose is a non reducing sugar because?
Correct answer: E. Both a and b
- A. It does not exist in open chain form
- B. Carbonyl groups are not free to reduce fehling's solution
- C. They have at least one free carbonyl group
- D. They form 1-4 glycosidic linkage
- E. Both a and b
Explanation
A sugar that serves as a reducing agent due to its free aldehyde or ketone functional groups in its molecular structure. Sucrose is a non-reducing sugar because the two monosaccharide units are held together by a glycosidic linkage between C1 of α-glucose and C2 of β-fructose. Sucrose has no aldehyde or ketone group to reduce Fehling's solution , so both options A and B are true. Hence the correct option is E

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
