Question

Why can Benedict's solution be used to distinguish between glucose and sucrose? A. Glucose is a reducing sugar, and sucrose is not a reducing sugar. B. Glucose is a carbohydrate, and sucrose is a protein. C. Benedict's solution turns orange in the presence of sucrose, but remains blue in the presence of glucose. D. Benedict's solution will release carbon dioxide bubbles from sucrose, but it cannot release carbon dioxide from glucose.

Answer 1

The correct answer to the question about why can a Benedict solution be used to distinguish between a glucose and a sucrose is letter A. Benedict's Solution is used to test the presence of reducing sugar. Glucose is a reducing sugar while Sucrose is a non-reducing sugar since it has a glycosidic bonds between their structure that hinders the formation of open chain. In the end, Sucrose stuck at its cyclic form.
