Tlhaloso ea Sehlahisoa:
N-Acetyl-L-cysteine ke phofo e tšoeu ea kristale e nang le monko o kang konofolo le tatso e bolila.
Hygroscopic, e qhibilihang ka metsing kapa ethanol, ha e qhibilihe ka har'a ether le chloroform. E na le asiti ka tharollo ea metsi (pH2-2.75 ka 10g/LH2O), mp101-107℃.
Ho sebetsa hantle ha N-acetyl-L-cysteine:
Li-antioxidants le li-reagents tsa mucopolysaccharide.
Ho tlalehiloe hore e thibela neuronal apoptosis, empa e baka apoptosis ea lisele tse boreleli tsa mesifa le ho thibela ho ikatisa ha HIV. E kanna ea ba substrate bakeng sa microsomal glutathione transferase.
E sebedisoa joalo ka sethethefatsi se qhalang li-phlegm.
E loketse tšitiso ea ho hema e bakoang ke palo e kholo ea tšitiso ea phlegm e khomarelang. Ho feta moo, e ka boela ea sebelisoa bakeng sa detoxification ea chefo ea acetaminophen.
Hobane sehlahisoa sena se na le monko o khethehileng, ho bonolo ho baka ho nyekeloa ke pelo le ho hlatsa ha u se nka.
