TL;DR: Dimethylarsinothioic acid was identified as a metabolite in urine and in wool extract from sheep naturally consuming large amounts of arsenosugars through their major food source, seaweed, and the structure was further confirmed by (1)H NMR, and ab initio tautomeric energy calculations showed it to be present as Me(2)As(=S)OH (dimethylars inothIOic acid).

TL;DR: Genetic variation at all field sites was a large determining factor for grain As concentration, indicating that cultivars low in grain As could be developed through breeding and that breeding strategies must take into account environmental factors.

TL;DR: The high values of digestibility measured, and the fact that North Ronaldsay sheep apparently are able to meet their energy needs from their seaweed diet, suggests that the use of these seaweeds as an alternative feed source for ruminants may be possible under some circumstances.

TL;DR: 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.

TL;DR: In this paper, the presence of inorganic Sb(III), a novel SbV-citrate complex, and a species tentatively identified as being non-complexed inorganic sb(V) in citrus fruit juices stored in PET bottles was reported.
