Homework Answers
DNS is ideal for measuring the action of enzymes such as
invertase, cellulase and amylase where reducing sugars are
produced.Hence, it is used in determination of concentration of
glucose.
Add Answer to:
In the determination of concentration of glucose, DNS is frequently used as a test reagent. Explain...

1. Show the chemical reaction that takes place when Benedict's reagent (Cu") reacts with glucose (use open chain Fisher projection). 2. Do you expect fructose to give a positive reaction with Barfoed's reagent? Explain why or why not. Indicate which of the test carbohydrates (glucose, fructose, lactose, sucrose, starch) would give 5- hydroxymethylfurfural when heated with hydrochloric acid. (See description of reactions for Barfoed's reagent and Seliwanoffs reagent). 3. 121
