N-Acetyl-L-cysteine; Ac-Cys-OH 616-91-1 is an acetylated amino acid with antioxidant and mucolytic properties. These two activities have made N-Acetyl-L-cysteine particularly relevant in cystic fibrosis studies, where the antioxidant/reducing character of the compound is described to ameliorate the characteristic systemic redox imbalance state of cystic fibrosis and the mucolytic properties of the compound are shown to impede upon the congestion and inflammation correlated to this redox state.
