The Correct Option is C
Solution and Explanation
Concept:
Vitamins are organic compounds, but some contain essential metallic elements in their core structure.
• Vitamin B12 is also known by its chemical name, Cobalamin.
• It features a corrin ring, which is structurally similar to the porphyrin ring.
Step 1: Analyzing the chemical name.
The name "Cobalamin" directly hints at the mineral hidden within the vitamin. "Cobal-" stands for the element Cobalt.
Step 2: Structural placement of the mineral.
A single atom of Cobalt sits at the very center of the corrin ring. This Cobalt atom is essential for the vitamin's biological activity in the body.
Step 3: Conclusion.
Vitamin B12 is the only vitamin known to contain a metal ion. Final Answer: (C)
