Test For Reducing and Non-Reducing Sugar
Specific chemical tests commonly used to differentiate between reducing and non-reducing sugars. The most widely used tests are the Benedictâs test for reducing sugars and the Hydrolysis test for non-reducing sugars.
Benedictâs Test (For Reducing Sugars)
A positive result is indicated by a color change from blue to green, yellow, orange, or red, depending on the concentration of reducing sugars. Example: Glucose, fructose, and maltose are reducing sugars and would give a positive Benedictâs test.
Hydrolysis Test (For Non-Reducing Sugars)
A positive result in the Benedictâs test after hydrolysis indicates the presence of non-reducing sugars that have been converted into reducing sugars. Example: Sucrose is a non-reducing sugar. After hydrolysis, it breaks down into glucose and fructose, both of which are reducing sugars.
Reducing vs Non-reducing Sugar
Reducing and non-reducing sugars are two categories of carbohydrates distinguished by their ability to undergo chemical reactions with other substances. Reducing sugars, like glucose and fructose, possess free aldehyde or ketone groups that enable them to undergo chemical reactions. In contrast, non-reducing sugars lack these groups and remain inert to such reactions. In this article, we will learn about reducing and non-reducing sugar, their examples, reactions, and differences.
