in mammals, excess cysteine is generally degraded by oxygenation to 3-sulfino-L-alanine. The majority of cysteine sulphinic acid is then deaminated to sulphinylpyruvate, which decomposes spontaneously byreleasing inorganic sulphite. The latter compound is then further oxidized to sulphate, which is excreted for the most part from the cell. In parallel, a variable proportion of cysteine sulphinic acid is decarboxylated to hypotaurine, then further oxidized to taurine. Although cysteine can be catabolized by some non-oxidative pathways, they are of minor importance. CDO activity is regulated by concentration of cysteine, and in mammals, both have been demonstrated to be important vital factors
