Arsenate is a chemical compound that contains arsenic in its +5 oxidation state, typically represented as AsO4^3-. It is commonly found in nature as a mineral and can also be produced through various industrial processes. Arsenate is often associated with environmental concerns, particularly in relation to soil and water contamination. In biological systems, arsenate can interfere with cellular processes, as it can mimic phosphate, a vital nutrient. This mimicry can disrupt energy production and other essential functions in living organisms. Due to its toxicity, arsenate is regulated in many countries to protect public health and the environment.
