In the process of studying for my upcoming biochemistry exam, I have stumbled over the classification of glycosidic bonds. I want to be able to distinguish $\alpha$- from $\beta$-glycosidic bonds. Unfortunately, even after reading through this page, I don't really understand how to go about classifying the bonds in e.g. an oligosaccharide.
Now, I am inclined to say that both of these anomeric linkages are of type $\alpha$, because the O-glycosidic bond is axial to the respective sugar rings. Is that a correct way of reasoning?
