Texts: 1. Define a reducing sugar. 2. Estimate the sensitivity limit (i.e., minimum concentration required for the detection of the test using glucose). 3. Give the detailed structural reaction with glucose for the Benedict's test. 4. Lactose is defined as a reducing sugar. Explain how this is possible using structural formulae to illustrate. 5. Which of the carbohydrates tested in the Benedict's test is strictly non-reducing? Explain using structural formulae and a written explanation.

Step 1
A reducing sugar is a type of sugar that has the ability to reduce other substances, particularly oxidizing agents. This is due to the presence of a free aldehyde or ketone group in its structure. When a reducing sugar reacts with an oxidizing agent, such as Show more…

Question 4 "Sugars that give a positive Benedicts test are called reducing sugar." i. Taking glucose as an example, explain in details the statement above and include all chemical reactions involve. (15 marks) ii. Fructose found to gives positive results to Benedict's test even the stucture does not reflect the reducing sugar characteristics. Using a diagram, explain what happened to these fructose during the test? (10 marks)
