Cyanocobalamine

/ˌsaɪ.ə.noʊ.koʊˈbæl.ə.miːn/ noun

Definition

An alternative spelling or form of cyanocobalamin, referring to vitamin B12 or related cobalt-containing compounds.

Etymology

From cyano- + cobalamine, a variant spelling of cobalamin. Used interchangeably with cyanocobalamin in older scientific literature and some non-English languages.

Kelly Says

The slight spelling variation reflects how different countries and scientific traditions named B12 differently as it was discovered—some emphasizing the cobalt-amine structure over the cyanide component.
