epimer

n. type of aldose compound (Chemistry)

In chemistry, an epimer is a stereoisomer of another compound that has a different configuration at only one of several stereogenic centers. Stereoisomers include enantiomers and diastereomers, both which contain a stereogenic center (excluding geometric isomers, which is a class of diastereomers).For example, the sugars α-glucose and β-glucose are epimers. In α-glucose, the -OH group on the first (anomeric) carbon is in the direction opposite the methylene group. In β-glucose, the -OH group is oriented in the same direction as the methylene group . These two molecules are both epimers and anomers.
