Ergothionein muaj cov teebmeem antioxidant

Ergothionein yog ib qho amino acid uas tau los ntawm cov nroj tsuag thiab tuaj yeem khaws cia hauv cov tsiaj. Cov kev tshawb fawb tau pom tias nws muaj cov tshuaj antioxidant. Nws tuaj yeem ua kom pom tseeb - OH, chelate divalent hlau thiab tooj liab ions, tiv thaiv H2O2 los ntawm kev tsim - OH nyob rau hauv qhov kev txiav txim ntawm hlau los yog tooj liab ions, thiab inhibit oxidation ntawm tooj liab dependent oxygenated hemoglobin. Nws tuaj yeem cuam tshuam cov tshuaj tiv thaiv peroxidation ntawm arachidonic acid uas tshwm sim thaum myoglobin (los yog hemoglobin) sib xyaw nrog H2O2. Ergothionein kuj tseem tuaj yeem tshem tawm cov kua qaub hypochlorous, yog li tiv thaiv qhov tsis ua haujlwm ntawm A1- antiprotease. Txawm li cas los xij, nws tsis tuaj yeem inhibit peroxidation cov tshuaj tiv thaiv ntawm lipid hais nyob rau hauv muaj cov hlau ions. AKanmu D et al. pom tias muaj qee qhov concentration ntawm ergothionein tuaj yeem ua raws li antioxidant hauv lub cev.
