Metabolite Identification
Common NameSulforaphane-N-acetylcysteine
DescriptionSulforaphane-N-acetylcysteine (SFN-NAC) is a metabolite of sulforophane which is a metabolite of glucoraphanin which is found in cauliflower and broccoli sprouts (PMID: 16166336 ; PMID: 21372038 ). It is excreted in urine. Glucoraphanin is a glucosinolate compound that is converted in the gut to sulforaphane, an isothiocyanate, by the action of myrosinase enzymes from the plants (PMID: 21372038 ). Sulforaphane blocks the initiation stage in carcinogenesis by inhibiting enzymes that convert procarcinogens to carcinogens and by inducing phase 2 enzymes that detoxify carcinogens and facilitate their excretion from the body.
