Answer: Stachyose, Sucrose, Verbascose, Trehalose and Raffinose are the five examples of non reducing sugars. Carbohydrate: A carbohydrate can be defined as a biomolecule that owns the atoms of hydrogen, oxygen and carbon. A carbohydrate usually contains hydrogen and oxygen atoms in the ratio of 2:1. The formula for this can be defined as Cn(H2O)n. The formula aforesaid holds appropriate for the monosaccharides. However, there exist some exceptions such as the Deoxyribose. It is a sugar component of DNA.
The classification of sugar can be done into two segments:
Reducing Sugars: These sugars are the carbohydrates that play the role of reducing agents because of the attendance of free ketone or free aldehyde groups in their structure. Every monosaccharide and a few of the disaccharides have been termed as reducing sugars. The oxidation of the reducing sugars can be done with the help of those compounds which are weak oxidizing agents. In the aqueous medium, the sugars of the reducing group give compounds that own the group of aldehydes.
Non-reducing Sugars: The compounds of carbohydrates because of the non-attendance of free ketone or free aldehyde groups do not act as the reducing agents in their structure. Only some of the disaccharides but all of the polysaccharides are the reducing sugars. The non-reducing sugars that have the aldehyde group cannot generate any compounds. The non-reducing sugars own acetal in the position of the hemiacetal. An acetal typically owns two O-R groups, one minus R group and one minus H group. These groups have been associated with the same carbon.
