[{"from": "human", "value": "Provide a brief overview of this molecule. [C][Se][Se][C]"}, {"from": "gpt", "value": "The molecule is an organoselenium compound that is diselane covalently bound to two methyl groups. It has been detected in onion-family vegetables and soft-necked garlics. It induces ER stress and toxic protein aggregation in the budding yeast, S. cerevisiae and used as a reagent to identify distonic radical cations. It has a role as a bacterial metabolite, a mammalian metabolite, a plant metabolite and a human xenobiotic metabolite."}]
