WebMicrobes may transform arsenic into different inorganic and organic forms [].Trivalent arsenite and pentavalent arsenate are the most abundant inorganic forms, with As(III) being 100 times more toxic than As(V) [].Arsenate toxicity is mainly derived from its ability to compete with phosphate oxyanions for both transport and energetic functions [], whereas … Web23. Pentavalent arsenate may substitute for phosphate-s> and bind to transferrin26-28. Most mammals methylate inorganic arsenic to the less reactive and more readily excreted metabolites methylarsonic acid (MMA) and dimethylarsinic acid (DMA cacodylic acid), but there are major differences in arsenic methylation between animal species and popu
