epimers are the class of stereoisomers which differ along configuration at any carbon in a carbohydrate(generally),
And anomers are the kind of stereo isomers that differ at the carbonylic carbon, which becomes achiral only after hemiacetal (hemiketal) formation
Websites on search give that Epimers are bigger group where Anomers are a part of them, but in certain books on biochemistry like that of Lippincott(d.ferrier) writers define Epimers as change in configuration at any carbon except anomeric carbon..
So are Anomers Epimers?
