Descriptions of N-acetyl-L-cysteine

N-acetyl-L-cysteine: A synthetic or naturally-occurring amino acid related to L-cysteine, a precursor of the antioxidant enzyme glutathione. Acetylcysteine regenerates liver stores of glutathione. This agent also reduces disulfide bonds in mucoproteins, resulting in liquification of mucus. Some evidence suggests that acetylcysteine may exert an anti-apoptotic effect due to its antioxidant activity. (NCI04)
