Product Details

N-Acetyl-L-cysteine CAS#616-91-1

N-Acetyl-L-cysteine is an N-acetylated derivative of cysteine, which contains a sulfhydryl group in the molecule, which can break the disulfide bond (-S-S-) of the mucin peptide bond, so that the mucin chain becomes a small molecule peptide chain, reducing The viscosity of mucin, so It is a dissolving drug for mucus in mucus, purulent sputum and respiratory tract.
