Aldose monosaccharides can be oxidized when treated with a mild oxidizing agent. In this reaction, the aldehyde group of the open-chain aldose is oxidized to a carboxylic acid group. In basic solution, ketose monosaccharides can also be oxidized, forming carboxylic acids because they can undergo a rearrangement to an aldose form. Monosaccharides (cyclic hemiacetals) can also react with an alcohol to form acetals, called glycosides, and water. In this reaction, the OH of the anomeric carbon is replaced by the OR group of the alcohol. D-ribose (Figure 1) is treated with a mild oxidizing agent. Edit the structure for D-ribose to show the product of this reaction. M Edit the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Include all hydrogen atoms. ► View Available Hint(s) [1] A H 12D H H H H 7 L EXP. CONT.i L 1 -O-H O H ew -O-H enodic Table -O-H H C N O S CI Br I P F
