WebJul 1, 2024 · The two structures have the same molecular formula and the same connectivity, therefore they must be stereoisomers. They each have four chiral centers, and the configuration is different at two of these centers (at carbons #3 and #4). They are diastereomers. Now, look at the structures of D -glucose and D -mannose.
