B12, or cobalamin, is a cobalt-containing coenzyme studied in enzymatic and metabolic research models.\u003c\/p\u003e\n\u003cp\u003eB12 is structurally remarkable among research materials: it is built around a corrin ring with a cobalt atom at the centre, giving the molecular formula C63H88CoN14O14P and a weight of 1355.37. It is the only cobalt-containing molecule in this catalogue.\u003c\/p\u003e\n\u003cp\u003eThat cobalt centre is what makes it chemically distinctive. Very few biological molecules incorporate the metal at all, and the carbon-cobalt bond found in some of its forms is among the rare examples of such a bond occurring in biochemistry.\u003c\/p\u003e\n\u003cp\u003eResearch using it concerns cobalamin-dependent enzyme systems and one-carbon metabolism, where it acts as a cofactor rather than as a signalling molecule. That places it in a different category from the receptor-binding peptides stocked alongside it.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCobalamin-dependent enzyme research\u003c\/li\u003e\n\u003cli\u003eOne-carbon metabolism pathway studies\u003c\/li\u003e\n\u003cli\u003eCorrin ring and organometallic chemistry\u003c\/li\u003e\n\u003cli\u003eCofactor rather than receptor-mediated models\u003c\/li\u003e\n\u003cli\u003eSolution stability and light sensitivity research\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e solution in a sealed research bottle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize available:\u003c\/strong\u003e 10ml\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack options:\u003c\/strong\u003e 1 bottle, 3 bottles, or 5 bottles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular formula:\u003c\/strong\u003e C63H88CoN14O14P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight:\u003c\/strong\u003e 1355.37\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRelated research material\u003c\/h2\u003e\n\u003cp\u003eAnother coenzyme stocked here is \u003ca href=\"\/products\/nad\"\u003eNAD+\u003c\/a\u003e.
