<unk>  is a condensation product formed from the coupling of cysteine with aromatic compounds. It is formed as a conjugate in the liver and is excreted in the urine. Glutathione adducts lose glutamate and glycine portions, and are acetylated to form<unk> s, which are excreted. Levels of<unk>  in the urine may be used as an indicator of exposure to, e.g., ethylene dibromide and acrylamide.
