Glucose and galactose are epimers, a specific subclass of diastereomers, differing in their configuration only around

A. Carbon 1
B. Carbon 2
C. Carbon 4
✓
D. Carbon 5

📝 Explanation

Epimers are sugars that differ in configuration at only one chiral center. Glucose and galactose are identical in structure except for the orientation of the hydroxyl group on C-4, making them C-4 epimers. Glucose and mannose are C-2 epimers.
