Diastereomer of d-glucose
WebMay 20, 2024 · Glucose and galactose are not cis isomers, but diastereomers called epimers, Two sugars that differ only in the configuration around one carbon atom are called epimers; D-glucose and D-mannose, which differ only in the stereochemistry at C-2, are epimers, as are D-glucose and D-galactose (which differ at C-4):
