The Correct Option is
Solution and Explanation
When gluconic acid (a sugar alcohol) is oxidized with nitric acid, the oxidation occurs at the aldehyde group of the molecule, converting gluconic acid to saccharic acid (also known as glucaric acid).
- Gluconic acid has a structure where an aldehyde group is oxidized to a carboxyl group upon reaction with nitric acid, leading to the formation of saccharic acid (C6H10O8).
- Other options such as glucose or fructose are sugars, and oxidation with nitric acid would not lead to saccharic acid, but rather to other oxidation products.
Thus, the correct answer is (E) saccharic acid.

Top Questions on Biomolecules
- Ribose and 2-deoxyribose have an important role in biology. Among the most important derivatives are those with phosphate groups attached at the 5 position. Mono-, di- and tri-phosphate forms are important, as well as 3-5 cyclic monophosphates. Purines and pyrimidines form an important class of compounds with ribose and deoxyribose. When these purine and pyrimidine derivatives are coupled to a ribose sugar, they are called nucleosides.
