Type: Term Pronunciation: ep′i-mĕr Definitions: 1. One of two molecules (having more than one chiral center) differing only in the spatial arrangement about a single chiral atom, α-d-glucose and α-d-galactose (with respect to carbon-4).Found on http://www.medilexicon.com/medicaldictionary.php?t=29842
In stereochemistry, epimer refers to one of a pair of stereoisomers. The two isomers differ in configuration at only one stereogenic center. All other stereocenters in the molecules, if any, are the same in each. Doxorubicin and epirubicin are two closely related drugs and epimers. The stereoisomers β-D-glucopyranose and β-D-mannopyranose are ep...Found on http://en.wikipedia.org/wiki/Epimer
