Is alpha-glucose a stereoisomer of beta-glucose?


Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space. 

Structural isomers have the identical chemical groups bonded to different carbon atoms. 

Stereoisomers have identical chemical groups bonded to the same carbon atoms with different orientations. 

Since alpha and beta glucose both have identical chemical groups bonded to the same carbon atoms, and only differ in the orientation of the H vs. OH at C1, YES, you could call them stereoisomers.
