an·o·mer

(an'ō-mer),
One of two sugar molecules that are epimeric at the hemiacetal or hemiketal carbon atom (carbon-1 in aldoses, carbon-2 in most ketoses), for example, α-d-glucose and β-d-glucose.

anomer

one of two stereoisomers (designated α or β) of the furanose or pyranose form of a sugar, e.g. α-d-glucose. α-forms have −OH group of the anomeric carbon below the plane of the furanose or pyranose ring.
