摘要：

Arsenic in sheep's clothing: the first characterization of a thio-organoarsenate compound (2-dimethylarsinothioyl acetic acid) isolated from a biological source (a rare breed of seaweed-eating sheep; see picture) is reported. The result indicates that mammalian arsenic metabolism is much more complex than has been claimed before, which opens up new questions about the toxicity of such organoarsenothio(y)l compounds.
