Vanadium is absorbed mainly via inhalation, though small amounts can be absorbed through the skin and gastrointestional tract. It is rapidly distributed in the plasma, mainly to the kidney, liver, lungs, heart, bone, where it tends to accumulate. With the help of cytochrome P-450 enzymes, it can interconvert between its two oxidation states, vanadyl (V+4) and vanadate (V+5). Both states of vanadium can reversibly bind to transferrin protein in the blood and then be taken up into erythrocytes. Vanadium is excreted mainly in the urine. (L837)

Sodium orthovanadate is often added to buffer solutions that are used in protein analysis in molecular biology. The aim is to preserve the phosphorylation of proteins of interest by inhibiting endogenous phosphatases present in cell lysate mixture. (L854)
