摘要

Methylation (the addition of methyl groups) of ingested inorganic arsenic to methylarsonic (MMA) and dimethylarsinic acids (DMA) occurs by enzymatic reactions that transfer the methyl group from S-adenosyl-methionine (SAM) to arsenic. Methylation of arsenic facilitates its urinary elimination and is considered a detoxification process. Because folate compounds play an important role in regulation of SAM levels, folate may also influence arsenic methylation and toxicity.
