What is trivalent arsenic?


What is trivalent arsenic?

Arsenite (trivalent arsenic) is considered to be the more toxic inorganic form compared to arsenate (pentavalent arsenic). Arsenite reacts with thiol and sulfhydryl groups, which are major organic components to multiple proteins and enzymes found throughout the body.

What is arsenic M?

Does DMSA remove arsenic?

The chelating agents DMPS, DMSA, and BAL offer therapeutic benefit in acute intoxication by arsenic and inorganic mercury salts if administered promptly (within minutes to hours). DMPS and DMSA have a higher therapeutic index than BAL and, unlike BAL, do not redistribute arsenic or mercury to the brain.

Does Glutathione remove arsenic from the body?

Glutathione (GSH) is an important redox molecule in cells, which can be used not only as a major antioxidant molecule to relieve arsenic-induced ROS [7] but also as a reductant involved in arsenic metabolism to promote arsenic excretion [8]. Therefore GSH plays an important role in inhibiting arsenism.
