JEE Mains · Chemistry · STD 12 - 10. Biomolecules
The incorrect statement from the following with respect to carbohydrates is:
- A All monosaccharides are reducing sugars.
- B The monosaccharide units obtained from hydrolysis of oligosaccharides are always the same.
- C Starch and cellulose are typical examples of polysaccharides, which are very high molecular weight compounds of more than ten monosaccharide units.
- D Open chain and cyclic structures co-exist at equilibrium that are responsible for certain properties as in the case of \(D-(+)\)-glucose.
Answer & Solution
Correct Answer
(B) The monosaccharide units obtained from hydrolysis of oligosaccharides are always the same.
Step-by-step Solution
Detailed explanation
Statement (A) is correct because all monosaccharides contain a free aldehyde or ketonic group (or exist in equilibrium with it) and act as reducing sugars. Statement (B) is incorrect because the hydrolysis of oligosaccharides can yield either the same or different monosaccharide…
