Everything about Cyanocobalamin totally explained

|Section2= |Section3= | ExternalMSDS = External MSDS from Fisher Scientific }} }} Cyanocobalamin is an especially common "vitamer" (that is, member of a family of vitamins, all of which have some particular nutritional activity in preventing some vitamin deficiency disease) of the B-12 vitamin family. It is the most famous vitamer of the family, because it's chemically the most air-stable, and it's the easiest to crystallize and therefore easiest to purify after it's produced by bacterial fermentation. The cyanide is added to the molecule by activated charcoal columns in purification. Thus, the use of this form of B-12 is the most wide-spread.
   This fact has caused some people (usually from reading labels on packages and vitamin supplements, in which vitamin B-12 is almost always listed last, since ingredients by law are listed in order of weight %), to infer that the "correct" chemical name of vitamin B-12 actually is cyanocobalamin. In fact, "vitamin B-12" is the name for a whole class of chemicals with B-12 activity, and "cyanocobalamin" is only one of these. Cyanocobalamin usually doesn't even occur in nature, and cyanocobalamin isn't one of the forms of this vitamin which is directly used in the human body (or that of any other animal). However, animals and humans can convert it to active (cofactor) forms of the vitamin, such as methylcobalamin.Further Information
