Practice: Which of the following pairs of sugars are epimers of each other?
Practice: The sugar α-D-Mannose is a sweet-tasting sugar. β-D-Mannose, on the other hand, tastes bitter. A pure solution of α-D-mannose loses its sweet taste with time as it is converted into the β anomer. Draw the β anomer:
Practice: Draw the α-furanose and β-pyranose forms of D-ribose.
Practice: Indicate if the following pairs of sugars are enantiomers, anomers, epimers, or an aldose-ketose pair:
