"vitamin B12 (cobalamin) is a complex structure and central to it is a cobalt ion within a corrin ring. Vitamin B12 is vital for the normal functioning of every cell in the human body, being key to DNA synthesis. Since vitamin B12 is a haematinic and cobalt is vital for its formation, it follows that cobalt is also one of the haematinics."
"Georg Brandt discovered cobalt in 1739 4. It was a difficult metal to extract from its ore cobaltite (an arsenosulfide) and attempts to do so resulted in miners falling ill (likely related to the arsenic found in this ore); these properties were attributed to goblins who had cast evil magic upon the rock. The German word for goblin, kobold, was subsequently adopted for this new element. Interestingly cobalt was the first metal to be discovered that was not known to the ancients."
"Bertrand and Macheboeuf first discovered cobalt in animal cells in 1925, this was later corroborated by more sophisticated spectrographic techniques."
"cobalt-57 is employed as a flood source to perform QA on gamma cameras in nuclear medicine departments"

"Cobalt is a shiny grey-silvery transition metal with an atomic number 27 and an atomic weight of 58.93 Daltons (Da). As with other metals it may be found in elemental, inorganic, and organic forms. Elemental cobalt is a solid, lustrous silver-grey metal with a melting point of 1495°C and a boiling point of 2927°C. Inorganic salts of cobalt occur in two oxidation states; cobaltous (2+) and cobaltic (3+). Organification of cobalt occurs in bacteria yielding cyanocobalamin."
