When ribose adopts a furanose structure which carbon is the anomeric carbon?

Question

Quizplus · Accepted Answer

In a furanose structure, the anomeric carbon is the carbon that is involved in forming the ring and is directly bonded to both an oxygen atom and another carbon atom. In the case of ribose, the furanose structure involves the oxygen on C-1 bonding to C-5, forming a five-membered ring with C-4 being incorporated into the ring. Therefore, C-1 is the anomeric carbon in ribose.
