Question: what are the differences in the haworth structures of α-d-glucose and β-d-glucose?
Answer: How do -D-glucose and -D-glucose differ? In α-D-glucose, the −OH on carbon 1 is down, whereas in β-D-glucose, the −OH is up. In α-D-glucose, the −OH on carbon 1 is up, whereas in β-D-glucose, the −OH is down.
