Aquacobalamin
Aquacobalamin is one of the major forms of vitamin B12 isolated from mammalian cells. Aquacobalamin accelerates the oxidation of azo-dye Orange II by HSO5- in aqueous solutions. Aquacobalamin binds hydrogen peroxide reversibly to form a cobalt (III) hydroperoxo adduct with a 0.25 mM dissociation constant[1][2][3].
