Consider the two monosaccharides shown below. Select all the terms that can be applied to these two molecules. Solution The monosaccharide shown are D-mannose and D-glucose. They have same structural formula:C6H12O6. Thus they are isomers. They differ only at C2. Thus they are epimers. All epimers are diastereoisomers => they are stereoisomers. Thus correct options are: 1,3,4,7. (Epimers, isomers, diastereoisomers, stereoisomers)..
