Taurine-nitrite interaction as a precursor of alkylation mechanisms

► Taurine molecule, present in nutraceuticals and energy drinks, undergoes nitrosation. ► In the nitrosation of taurine, ethanesultone and isethionic acid are formed. ► Ethanesultone shows alkylating capacity over a DNA model molecule. ► Human stomach conditions could be a favorable medium for taurine nitrosation.
