The structure that are differ with each other at only one chrial carbon position is called epimer. A fine example of epimer is the glucose and galactose which differ from each other at position of hydroxyl group at C4. As we can see the difference in glucose and glaactose at 2 caron atoms, so these are not epimers. In case of glucose and galactose there is difference at only one carbon so these are epimers. There are epimers at carbon number 4.
