Reducing and Non-Reducing Sugar Examples

Reducing sugars are commonly found in fruits, some vegetables, and processed foods containing glucose or fructose. Non-reducing sugars are often found in complex carbohydrates such as starche and cellulose.

Reducing Sugars Examples

  1. Glucose: A monosaccharide and a primary source of energy for living organisms.
  2. Fructose: Another monosaccharide commonly found in fruits and honey.
  3. Maltose: A disaccharide composed of two glucose molecules. It is produced during the digestion of starch.
  4. Lactose: A disaccharide composed of glucose and galactose. It is found in milk.

Non-Reducing Sugars Examples

  1. Sucrose: A disaccharide composed of glucose and fructose. It is commonly known as table sugar .
  2. Trehalose: Trehalose is a disaccharide composed of two glucose molecules linked by an α,α-1,1-glycosidic bond.
  3. Raffinose: Raffinose is a trisaccharide composed of galactose, glucose, and fructose.
  4. Gentianose: Gentianose is another trisaccharide composed of three glucose molecules.
  5. Verbascose: Verbascose is a tetrasaccharide composed of four glucose molecules.

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.

Definition of Reducing and Non-Reducing Sugar

Reducing sugars contain free aldehyde or ketone groups, allowing them to undergo chemical reactions, while non-reducing sugars lack these groups and remain chemically inert....

What is Reducing Sugar?

A reducing sugar donates electrons to another chemical substance and is characterized by a free aldehyde or ketone group in the sugar molecule. These functional groups can undergo oxidation-reduction reactions. An example includes glucose and maltose. They have an open-chain form with an aldehyde group or a free hemiacetal group. The anomeric carbon of sugar can be used to identify the sugar type. It is a reducing sugar if it has an OH group in its anomeric carbon....

What is Non-Reducing Sugar?

A non-reducing sugar, does not have a free aldehyde or ketone group and, therefore, cannot donate electrons in a redox reaction. All the carbonyl groups of the non-reducing sugar are involved in glycosidic linkages, thus forming a closed ring that prevents the molecule from acting as a reducing agent. Some examples of non-reducing sugars includes, Stachyose, Sucrose, Verbascose, Trehalose, Raffinose, Gentianose. Non-reducing sugars can be converted into reducing sugars through acid hydrolysis or enzymatic hydrolysis....

Conclusion – Reducing and Non-Reducing Sugar

In conclusion, reducing sugar are a form of carbohydrate that possess free aldehyde or ketone group(s) as functional group and can reduce other substances. It can donate electrons or hydrogen atoms, and act as reducing agents. Examples of reducing sugars include glucose, lactose, and maltose. On the other hand, Non-reducing sugars lack a free aldehyde or ketone group and, therefore, does not participate in the redox reaction. It can not donate electrons or hydrogen atoms. Sucrose is a common example of a non-reducing sugar. Distinguishing sugars into reducing and non-reducing is a fundamental concept in biochemistry and food chemistry....
