What
is Cyanocobalamin? Cyanocobalamin is a manufactured form of vitamin B12.
Vitamin B12 is an essential nutrient meaning that it cannot be made by the body
but is required for life.
Cyanocobalamin
Chemistry Vitamin B12 is the “generic descriptor” name for any vitamers of
vitamin B12. Animals, including humans, can convert cyanocobalamin to any one
of the active vitamin B12 compounds.
Cyanocobalamin
is one of the most widely manufactured vitamers in the vitamin B
12
family (the family of chemicals that function as B12 when put into the body),
because cyanocobalamin is the most air-stable of the B12 forms. It is the
easiest to crystallize and therefore easiest to purify after it is produced by
bacterial fermentation. It can be obtained as dark red crystals or as an
amorphous red powder. Cyanocobalamin is hygroscopic in the anhydrous form, and
sparingly soluble in water (1:80).
Production
of Cyanocobalamin Cyanocobalamin is commercially prepared by bacterial
fermentation. Fermentation by a variety of microorganisms yields a mixture of
methylcobalamin, hydroxocobalamin, and adenosylcobalamin. These compounds are converted
to cyanocobalamin by addition of potassium cyanide in the presence of sodium
nitrite and heat. Historically, the physiological form was initially thought to
be cyanocobalamin. This was because hydroxocobalamin produced by bacteria was
changed to cyanocobalamin during purification in activated charcoal columns
after separation from the bacterial cultures.
