The structure of vitamin B12 is shown earliar. As you may have noticed, vitamin B12 is the largest of the B complex vitamins. It consists of a corrin ring made up of four pyroles with cobalt at the centre of the ring. There are several vitamin B12-dependent enzymes in bacteria and algae, but no species of plants have the enzymes necessary for vitamin B12 synthesis.
