Metabolite Identification
Common NameHypotaurine
DescriptionHypotaurine belongs to the class of organic compounds known as sulfinic acids. Sulfinic acids are compounds containing a sulfinic acid functional group, with the general structure RS(=O)OH (R = organyl, not H). Hypotaurine is possibly soluble (in water) and a very strong basic compound (based on its pKa). Hypotaurine exists in all living species, ranging from bacteria to humans. Hypotaurine participates in a number of enzymatic reactions, within cattle. In particular, Hypotaurine can be biosynthesized from cysteamine through the action of the enzyme 2-aminoethanethiol dioxygenase. In addition, Hypotaurine can be biosynthesized from 3-sulfinoalanine; which is catalyzed by the enzyme cysteine sulfinic acid decarboxylase. In cattle, hypotaurine is involved in the metabolic pathway called the taurine and hypotaurine metabolism pathway.
