http://www.chem.ucla.edu/~harding/IGOC/H/haworth_projection.html WebSame rules apply. If the group is cis with respect to the sixth carbon, it's beta. Of course if it's trans, it would be an alpha linkage. In this case, our OR group, which the OR group is this whole carbohydrate, is cis with respect to the C6 carbon. So we have a beta one, four glycosidic linkage.
