Vanadium in Biological Systems Vanadium is abundant in the biosphere, where it has a well-defined function in some biological systems. It also has pharmacological effects in other systems (see Chapter 11) and is listed in modern nutrition books as being a required ultra trace metal. Vanadium, the twenty-third member of the periodic table, is a soft ductile, silver-gray metal. The transitional element has occupied a place, which belongs to group VB and fourth period in the periodic table. Vanadium is widely distributed throughout the planet but low in abundance. The first comprehensive resource on the chemistry of vanadium, Vanadium: Chemistry, Biochemistry, Pharmacology, and Practical Applications has evolved from over a quarter century of research that concentrated on delineating the aqueous coordination reactions that characterize the vanadium(V) oxidation state. The authors distill information on biological processes needed to understand vanadium effects in biological systems Cited by: A systematic study of the physiologically interesting vanadium−maltol (V−MaH) system has been performed in M Na(Cl) at 25 °C, using NMR, ESR, and potentiometric techniques. Complexation occurs within a wide pH range, from around 1 up to However, a pH-, concentration-, and time-dependent spontaneous reduction of vanadium(V) to vanadium(IV) occurs. From ESR spectra the.

Vanadium compounds have been proven to be associated with various implications in the pathogenesis of some human diseases and also in maintaining normal body functions. Salts of vanadium interfere with an essential array of enzymatic systems such as different Cited by: Vanadium is special in at least two respects: On the one hand, the tetrahedral anion vanadate(V) is similar to the phosphate anion; vanadate can thus interact with various physiological substrates that are otherwise functionalized by : Dieter Rehder. Vanadium is a trace element and exists in biological systems, both as a required element and as a mimic of other required metal ions or phosphorus. Several classes of enzymes contain vanadium in the active site, including vanadium-dependent haloperoxidases, vanadium-containing nitrogenases, and vanadium-binding proteins, vanabins.   The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties.

Vanadium is an element of group Vb of the periodic system and belongs to the first transition series. It forms compounds mainly in oxidation states +3, +4, or +5. The most stable oxidation state is +4, in which vanadium forms oxovanadium(IV) ion (vanadyl).   The Learning Objective of this Module is to describe some of the roles of trace elements in biological systems. Given the low levels of tin in mammals ( mg/70 kg human), tin is unlikely to function as a macromineral. predict a likely biological function for vanadium. The authors distill information on biological processes needed to understand vanadium effects in biological systems and make this information accessible to a wide range of readers, including chemists without extensive biological training.
