2) testing for sugars

What is the test for reducing sugars?

1) add benedicts reagent

2) heat

3) a positive test observation = blue ,g,y to brick red

( the more red, the higher conc of reducing sugar)

Test for non reducing sugar

Following a negative benedicts test, where reagent remains blue

1)add acid + boil = acid hydrolysis

2) cool the solution

3) add alkaline to neutralise solution

4) add benedicts reagent

6) heat

7) positive test = blue to brick red

( the more red, the higher conc of reducing sugar)

What is the result for testing reducing and non reducing sugars?

Blue to brick red
