What is N-Acetyl-L-cysteine?It has a garlic-like odor and a sour taste. It is acidic in aqueous solution (pH2-2.75 in 10g/ lH2O), mp101-107 ° C. It is a N-acetylated derivative of cysteine, containing sulfhydryl groups, which can break the disulfide bond (-S-S-) of mucin peptide bond, thus making mucin chain into small molecule peptide chain and reducing the viscosity of mucin. Therefore, Chemicalbook is a solvent for mucin, purulent sputum and respiratory mucus.
Application & Function 1. The sulfhydryl group (-SH) contained in the molecule can break the disulfide chain (-S-S) which connects the mucin peptide chain in mucin. Mucin turns into small molecule peptide chains that reduce the viscosity of sputum; It can also break the DNA fibers in purulent sputum, so it can dissolve not only white mucous sputum but also purulent sputum.
2.In medicine, it is used as a mucinous dissolving drug. Used in biochemical research, as a phlegm dissolving drug and an antidote to acetaminophen poisoning.
3. Used in biochemical research, as a phlegm dissolving drug and an antidote to acetaminophen poisoning.
4.It is suitable for acute and chronic respiratory diseases with thick sputum and difficult to cough up, as well as serious symptoms caused by massive mucous sputum obstruction.
