in which X is S or Se and G is a moiety such as an aminoacid, a di- or tripeptide, or a lipid. The compounds have been characterized by NMR, mass spectroscopy, and elemental analysis. Cysteine was found to react directly with dimethylarsinic acid to yield cystine and S-dimethylarsinocysteine (1). This reaction occurs also with other biomolecules containing thiol groups and raises serious questions
