Metabolism of N-acetyl-L-cysteine. Some structural requirements for the deacetylation and consequences for the oral bioavailability

Rat liver, lung and intestine homogenates deacetylated N-acetyl-L-cysteine. Nearly stoichiometric amounts of L-cysteine were recovered. In rat liver, the enzyme activity was associated with the cytosolic fraction. Liver cytosol was much less active. N-Acetyl-D-cysteine or the disulphide of N-acetyl-...
