Question

Identify the wrong match in the following

• A. Glucose - sorbitol
• B. Fructose - soluble calcium salt
• C. Sucrose - dextrorotatory
• D. Sucrose hydrolysis - levorotatory

Answer 1

The correct option is B Fructose - soluble calcium salt

• Sorbitol is obtained by reduction of glucose.
• Sucrose is dextrorotatory and sucrose hydrolysis forms a levorotatory compound.
  
• Fructose is not a soluble calcium salt but is a ketonic monosaccharide.
• It exists in foods either as a monosaccharide (free fructose) or as a unit of a disaccharide (sucrose). Free fructose is absorbed directly by the intestine.

Thus the correct answer is option B.
