A sugar that is C − 3 epimer of D-xylose is to be stated. Concept Introduction: Epimers are the monosaccharides which differ in the structure at only one of the asymmetric center and they are particular kind of stereoisomers that are not enantiomers. For example, D-xylose and D-ribose are the C − 3 epimers because they differ in the configuration only at carbon number 3 starting from the above rest whole structure is same.
