The oxidation of hypotaurine to taurine: bis-aminoethyl-alpha-disulfone, a metabolic intermediate in mammalian tissue.
The primary mammalian metabolic pathway leading to taurine is generally recognized as beginning with the oxidation of cysteine to cysteine sulfinate via cysteine dioxygenase (19). This rate limitingExpand
