검증된 단계별 안내1
Identify the structure of vitamin B12, which is also known as cyanocobalamin.
Understand that vitamin B12 is a complex organometallic compound with a cobalt ion at its center.
Recognize that the 'cyano' part of cyanocobalamin refers to the presence of a cyanide group (CN) attached to the cobalt ion.
Note that the cyanocobalamin group is unique to vitamin B12 and is not a common functional group like hydroxyl, amino, or carboxyl groups.
Conclude that the functional group specific to vitamin B12 is the cyanocobalamin group, which includes the cyanide ligand bound to cobalt.
