An alternative or variant spelling of cobalamin, referring to vitamin B12 or related compounds containing a cobalt atom.
From 'cobalt' + '-amine' (a chemical suffix), with the '-e' ending used in some compound names. This represents a slightly different chemical nomenclature convention used in older or regional scientific literature.
You'll see both 'cobalamin' and 'cobalamine' in older scientific papers and some international textbooks, which shows how chemical naming can vary even for the same molecule—it's like how different countries might spell the same word differently!
