Which one of the following is a non - reducing carbohydrate? [2014...
Non-Reducing Carbohydrates:
Carbohydrates are classified into two categories based on their reducing properties - reducing and non-reducing carbohydrates.
Reducing carbohydrates are those that can donate electrons or reduce other substances, while non-reducing carbohydrates cannot donate electrons or reduce other substances.
The reducing property of carbohydrates is due to the presence of a free aldehyde or ketone group that can donate electrons, while non-reducing carbohydrates lack a free aldehyde or ketone group.
Examples of non-reducing carbohydrates include sucrose, trehalose, and cellulose.
Sucrose as a Non-Reducing Carbohydrate:
Sucrose is a disaccharide composed of glucose and fructose units joined by a glycosidic bond. It is a non-reducing carbohydrate because it lacks a free aldehyde or ketone group.
When sucrose is hydrolyzed, it breaks down into its constituent monosaccharides, glucose, and fructose. However, unlike reducing sugars, sucrose does not react with Benedict's reagent or Tollens' reagent because it lacks a free aldehyde or ketone group to reduce these reagents.
Therefore, sucrose is classified as a non-reducing carbohydrate.
