I think it's the structure. In alpha glucose the OH is pointing up and in beta it is pointing down. It might be wrong but I'm pretty sure it has something to do with the structure.

In beta linkages which refers to cellulose, the bonding OH's alternate from above and below the plane. The monomers are two glucose unit bonded with OH below the plane while the OH bonds between monomers are above the plane.
Alpha linkages which is just starch have all OH below the plane.
its not like graphite and diamond because thats an isotope. this is an isomer, i think.

the difference is in the hydroxy groups... i think it is 1 and 4kaz1 said:

Spot the difference.

The difference between the two isomers is that the OH (attached to the carbon next to the O atom) sticks out either opposite or on the same side to the OH on the adjacent carbon. (i.e. the OH on carbon 1 and OH on carbon 2 are on the same "side" in space for alpha and are on opposite "sides" to each other in space for the beta)
