WebMar 5, 2024 · All that has changed is the shape of the molecule. As shown for glucose, one can see that the beta-hydroxyl of glucose is closer to the \(CH_2OH\) (carbon #6) in the boat form than it is in the chair form. Steric hindrance can be a factor in favoring one configuration over another.
