Sprenkle The most prominent biological importance of vanadium is its presence, in the form of vanadate(V), as a constituent of the active centre of many haloperoxidases in marine algae. The physiologically important functions are based upon the similarity between phosphate [HPO4]2- and the vanadates(V and IV), [H2VO4]- and [VO(OH)3] . This similarity leads to the regulation (and, at higher vanadium doses, inhibition) of many phosphate metabolising enzymes (such as phosphatases, kinases and.

Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO] 2+ and in alkali to give the brown [V 4 O 9] 2− ion, or at high pH [VO 4] 4−. VO 2 has a phase transition very close to room temperature (~66 °C) Synonyme: Vanadium(IV) etioporphyrin III oxide;Vanadium-etioporphyrin-III-oxide. CAS-Nummer: 15709-03-2.
