Question

Which of the following are true ? A. All the monosaccharides except dihydroxyacetone contain one or more asymmetric carbon atoms.
B. Sucrose is a disaccharide consisting of D-glucose and D-fructose.
C. Sugars capable of reducing cupric ions are called reducing sugars.
D. Starch is the main storage polysaccharide of animal cells.
E. The rigid bacterial cell wall is made up of cellulose.
Choose the correct answer from the options given below :

• A. \(A, C\) only
• B. \(A, B, C\) only
• C. \(A, D\) only
• D. \(E, C\) only

Hint:

Remember:
• Sucrose \(=\) Glucose + Fructose
• Glycogen \(\rightarrow\) Animal storage polysaccharide
• Starch \(\rightarrow\) Plant storage polysaccharide
• Peptidoglycan \(\rightarrow\) Bacterial cell wall \[ \text{Reducing sugars reduce } Cu^{2+} \text{ in Benedict's/Fehling's test} \]

Answer 1

The Correct Option is B
