What indicator do we use to test for the presence of monosaccharides (glucose)?
A
Biuret’s
B
Sudan III
C
Lugol’s/Iodine
D
Benedict’s
Explanation: 

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: -Benedict’s solution can be used to test for the presence of glucose in urine. When glucose is mixed with Benedict’s reagent and heated, a reduction reaction causes the Benedict’s reagent to change color. The color varies from green to dark red (brick) or rusty-brown, depending on the amount of and type of sugar.
