What are α-D-glucose and β -D-glucose?

C is the answer to this question. Those who have always loved chemistry will have no trouble figuring out what anomers are. Anomers are found in different atoms of carbohydrates. Some people may get confused if they are dealing with anomers or epimers. It should be noted that their configuration is different from each other.

You would know if you are dealing with an anomeric carbon based on the direction of the OH group that is attached to the carbon. It can be α or β. How will you know? Just look at the direction where the OH group is located.
