N-Acetyl Cysteine

An Amino Acid


N-acetyl cysteine (NAC) is a low molecular weight nucleophilic thiol which forms glutathione, cystine, l-methionine and mixed disulfides. Oral administration of NAC elevates levels of reduced glutathione in the liver, in the bronchial and alveolar fluid and in plasma. Cystine is the stable form of cysteine and the body uses them interchangeably and is therefore thought of as the same molecule.
