Vanadium

Journal of Toxicology: Clinical Toxicology, 1999
Vanadium is a steel-grey, corrosion-resistant metal, which exists in oxidation states ranging from -1 to +5. Metallic vanadium does not occur in nature, and the most common valence states are +3, +4, and +5. The pentavalent form (VO3-) predominates in extracellular body fluids whereas the quadrivalent form (VO+2) is the most common intracellular form ...

Vanadium Haloperoxidases

Current Opinion in Chemical Biology, 1998
The nature of the oxidized halogen intermediate in vanadium bromoperoxidase has recently been shown to depend on the nature of the organic substrate. For example, in the presence of indoles, vanadium bromoperoxidase does not release a freely diffusible oxidized halogen intermediate (such as HOBr+/-BR2+/-Br3-).

Vanadium nitrogenase

Journal of Inorganic Biochemistry, 2000
The topic, vanadium nitrogenase, is reviewed with respect to biological characteristics and findings on its structure and functions. Structural models (vanadium complexes containing ligands related to the active center in the iron-vanadium cofactor) and functional models for the reductive protonation of dinitrogen, the activation of alkynes and ...

Vanadium biochemistry

2007
Vanadium has long been known to mimic or to enhance insulin activity. It was estimated that by the year 2025 about 300 million people would suffer from diabetes mellitus. Diabetic patients are also subject to other pathologies such as nephropathy, arterial and neurodegenerative diseases.
