Various cysteine derivatives were studied to determine if they would be superior to cysteine in removing NO from flue gas. These include glutathione (a tripeptide) and glyclcysteine (a dipeptide) which are the subject of this study. Glutathione (glutamylcysteinylglycine, abbreviated GSH) is a thiol compound that is abundant in living cells. It is composed of the amino acids glutamic acid, cysteine and glycine linked by peptide bonds. Cysteine is the central amino acid. In a manner similar to cysteine, GSH can be oxidized to the disulfide (noted as GSSG). Glyclcysteine is readily produced by the acid hydrolysis of GSH. It also forms a disulfide when oxidized.
