Question

Is ribose a ketose sugar?

Answer 1

1. The simple sugar ribose has a chemical formula(${\mathbf{C}}_{\mathbf{5}}{\mathbf{H}}_{\mathbf{10}}{\mathbf{O}}_{\mathbf{5}}$).
2. The aldoses are monosaccharides with the $\left(\mathbf{CHO}\right)$aldehydic group, whereas the ketoses are monosaccharides with the($\mathbf{C}\mathbf{=}\mathbf{O}$) ketonic group.
3. The number of carbon atoms in a sugar chain is used to classify triose, tetrose, pentose, hexose, heptose, and other sugars.
4. Ribose,(${\mathbf{C}}_{\mathbf{5}}{\mathbf{H}}_{\mathbf{10}}{\mathbf{O}}_{\mathbf{5}}$), is a simple sugar having an aldehyde group with a chemical formula(${\mathbf{C}}_{\mathbf{5}}{\mathbf{H}}_{\mathbf{10}}{\mathbf{O}}_{\mathbf{5}}$).
5. The structure of ribose is given as-

Hence, ribose is not a ketose sugar.
