The ion VO4^3-, known as the vanadate ion, consists of one vanadium atom surrounded by four oxygen atoms. It carries a negative charge of three, making it an anion. Vanadate is commonly found in various chemical compounds and plays a role in biological systems, particularly in enzyme activity. Vanadate is often used in laboratory settings as a reagent and is studied for its potential applications in catalysis and materials science. It can also mimic phosphate in biological processes, which has led to research into its effects on cellular functions and signaling pathways.
