Metabolite Identification
Common NameSelenate
DescriptionSelenate, also known as selenic acid, is a member of the class of compounds known as non-metal selanates. These are inorganic non-metallic compounds containing a selenate as its largest oxoanion. Selenate can be found in a number of foods such as chives, naranjillas, moth beans, other soy products, black crowberries, rapes, acorns, and Alaska blueberries. Selenates are analogous to sulfates and have similar chemistry (Wikipedia). They are highly soluble in aqueous solutions at ambient temperatures (Wikipedia). Selenate can be metabolized to methyl-2-acetamido-2-deoxy-1-seleno-β-D-galactopyranoside (SeSug1) and methyl-2-amino-2-deoxy-1-seleno-β-D-galactopyranoside (SeSug3) (PMID: 25270623 ). Selenate is metabolized only marginally and is excreted rapidly via urine generally (PMID: 25270623 ). Sodium selenate is effectively used for bio-fortification of crops hence fortifying food/feed to mitigate selenium deficiency in humans and livestock (Wikipedia). The decahydrate is a common ingredient in multivitamins and livestock feed as a source of selenium (Wikipedia).
