Detailed explanation-1: -We can use a special reagent called Benedict’s solution to test for simple carbohydrates like glucose. Benedict’s solution is blue but, if simple carbohydrates are present, it will change colour – green/yellow if the amount is low and red if it is high.

Detailed explanation-2: -Sucrose gives a negative test (blue) to the Benedict solution. Another example of a non-reducing sugar are the so-called “glucosides” of common sugars, such as glucose methyl glucoside, below.
