Maltose is a disaccharide that made of 2 glucose units. Each
glucose unit can happen as alpha or beta. So, "α" or "β" is
grounded on the relation between the stereochemistry of the anomeric carbon and
the furthest chiral center in the ring. The α anomer is the one in which these
two locations have the same configuration; they are opposite in the β anomer.
