Gabatarwa
Hydroxycobalamin (ohcbl, ko B12a) wani nau'i ne na bitamin B12, ko ?aya daga cikin azuzuwan bitamin B12. Memba ne na asali na ?ungiyar cobalamine. Yawancin kwayoyin cutar da ke samar da bitamin a kasuwa suna samar da bitamin B12 a cikin hanyar hydroxycobalamin. Hydroxycobalamin yana da duhu ja. Vitamin B12 a cikin jikin mutum ba ya kasancewa a cikin hanyar hydroxycobalamin. Koyaya, a cikin mutane, ana iya juyar da hydroxycobalamin cikin sau?i zuwa nau'in coenzyme mai amfani na bitamin B12. Samfurin hydroxycobalamin na magani shine allurar bakararre, wanda ake amfani dashi don magance rashi bitamin da guba na cyanide (saboda ya dace da ions cyanide).
