Metabolite Identification
Common NameTellurium
DescriptionTellurium is a trace element that belongs chemically to the VIa group in the periodic chemical table that has the symbol Te and atomic number 52. Tellurium is a brittle silver-white metalloid which looks like tin, and is related to selenium and sulfur. Physiologically, it exists as an ion in the body. The ingestion of tellurium compounds has been known to be associated with a garlic-like odor of the breath, thus indicating that tellurium is absorbed by the gut, metabolized by tissues, and excreted through routes other than the feces. Little is known about the Te biological activity, particularly with respect to potential chemical interactions with Se-containing components in the organism. Tellurium is a non-competitive inhibitor of squalene epoxidase and has been associated with neuropathy. Late fetal stages of prenatal development appeared uniquely sensitive to organic tellurium exposure. All tellurium compounds are highly toxic. (PMID: 17873396 , 15596254 , 10048717 ).
