Cyanocobalamin
(重定向自Animal Protein Factor)




Cyanocobalamin is a synthetic form of vitamin B12. Vitamin B12 is the "generic descriptor" name for any of such vitamers of vitamin B12. Because humans and animals can convert cyanocobalamin to any one of the active vitamin B12 compounds, by definition this makes cyanocobalamin itself a form (or vitamer) of B12.
