Metabolite Identification
Common NameHydrogen sulfite
DescriptionSulfite, also known as sulphurous acid or [so(OH)2], belongs to the class of inorganic compounds known as non-metal sulfites. These are inorganic non-metallic compounds containing a sulfite as its largest oxoanion. Sulfite is a moderately acidic compound (based on its pKa). Sulfite exists in all living species, ranging from bacteria to humans. In cattle, sulfite is involved in the metabolic pathway called the cysteine metabolism pathway. Sulfite is a potentially toxic compound.
