Methylarsonite

Monomethylarsonous acid

CH5AsO2 (123.9505)


Methylarsonite is found in the arsenate detoxification I pathway. Two molecules of glutathione reacts with methylarsonate to produce glutathione disulfide and methylarsonite. Methylarsonate reductase catalyzes this reaction. Methylarsonite reacts with S-adenosyl-L-methionine to produce S-adenosyl-L-homocysteine and dimethylarsinate. Methylarsonite methyltransferase catalyzes this reaction. Methylarsonite is found in the arsenate detoxification I pathway.
