These are inorganic compounds in which the largest oxoanion is phosphoroselenoic acid, and in which the heaviest atom not in an oxoanion is a non-metal element. Phosphoroselenoic acid is possibly soluble (in water) and an extremely strong acidic compound (based on its pKa). Phosphoroselenoic acid exists in all living organisms, ranging from bacteria to humans. Phosphoroselenoic acid can be biosynthesized from hydrogen selenide; which is mediated by the enzyme selenide, water dikinase 2. In cattle, phosphoroselenoic acid is involved in the metabolic pathway called the selenoamino acid metabolism pathway.
