IMISEBENZI YAMAHHALA NEZIFO

 

Imvamisa, ama-radicals amahhala ayadingeka emizimbeni, kepha ama-radicals wamahhala ngokweqile angadala ukungalingani kokusebenza komzimba, bese kuholela ekucindezelekeni kwe-oxidative okuvela ezifweni ezahlukahlukene (imibhalo ekhombisa ukuthi ama-radicals amahhala angumthombo wezifo ezahlukahlukene).

I-ANTIOXIDANT

 

Imizimba yethu ayikwazi ukusebenza ngaphandle komoya-mpilo, futhi uma inani elikhulu lama-radicals amahhala lenyuka, umzimba ongaphansi kwengcindezi ye-oxidative uzokwenza ukuthi uhlelo lokulungisa lwehluleke ekususeni ama-radicals wamahhala ngokweqile. Ezimweni ezikhethekile, umzimba udinga ukugcwalisa ama-antioxidants in vitro ukususa ama-radicals wamahhala ngokweqile.

L-ERGOTHIONEINE -UHLOBO OLUSHA LWE-ANTioxidant Yemvelo

 

Umhl iyi-chiral yemvelo i-amino-acid antioxidant biosynthesized kumagciwane athile nesikhunta. Kuyinhlanganisela ebalulekile ye-bioactive esetshenziswe njenge-scavenger enamandla, isihlungi se-ultraviolet ray, umlawuli we-oxidation-reduction reaction kanye ne-bioenergetics yeselula, kanye ne-cytoprotector yomzimba, njll.
I-L-Ergothioneine (i-EGT, i-ERGO, i-CAS: 497-30-3), eyaziwa nangokuthi (S) -cy-Carboxy-2,3-dihydro-N, N, N-trimethyl-2-thioxo-1H-imidazole- Usawoti wangaphakathi we-4-ethanaminium, ekuqaleni wakhishwa ku-ergot nguTanret C ngonyaka ka-1909, wabe usutholakala egazini lesilwane. I-EGT emsulwa iyikristalu emhlophe, inyibilika emanzini, (ichithwe u-0.9mol / L endaweni yokushisa yasekamelweni). I-Autoxidation ayikwazi ukwenzeka ngenani le-pH yemvelo noma kusisombululo se-alkali esinamandla. I-EGT ingaba khona ngezindlela ezimbili ze-isomer - ifomu le-thiol nefomu le-thione, njengoba kukhonjisiwe ngezansi:

Ngezinzuzo zemisebenzi eminingi, Umhl ivelele phakathi kwamanye ama-antioxidants amaningi.

UBUHLE

Kungenalutho

Ngezinzuzo zemisebenzi eminingi, i-EGT ivelele phakathi kokunye okuningi AntioxidantsIzinzuzo (uma kuqhathaniswa ne-glutathione, cysteine ​​njll.):
——EGT kulula ukuyiqongelela kumaseli futhi ukuhlushwa kuzinzile ukwedlula amanye ama-antioxidants.
———EGT isebenza ngempumelelo ekunciphiseni ukufa kweseli okubangelwa i-pyrogallol.
——EGT ikakhulukazi ihlasela i-ROS ukuvimbela i-oxidation, kuyilapho i-glutathione nabanye bethwebula ama-radicals wamahhala, okusho ukuthi, okunye Antioxidants scavenge imikhiqizo ye-oxidation.(1) Oleoylethanolamide (oea) - induku yemilingo yempilo yakho

Ukuqhathaniswa KOKUFANYELELA

Ezenye: Umhl ibingumdwebi osebenza kakhulu wama-radicals wamahhala uma kuqhathaniswa nama-antioxidants akudala njenge-GSH, i-uric acid ne-trolox. Ikakhulu, umthamo ophakeme kakhulu we-antioxidant okhonjiswe yi-EGT vs. peroxyl radicals uholele ngama-25% aphezulu kunenani elitholwe ngereferensi antioxidant trolox. Umthamo wokukhwabanisa we-EGT maqondana ne-hydroxyl radicals wawungaphezulu ngama-60%, uma kuqhathaniswa ne-uric acid, emele ireferensi antioxidant vs. hydroxyl radicals. Ekugcineni, i-EGT ikhombise umsebenzi ophakeme kakhulu we-antioxidant futhi maqondana ne-peroxynitrite, enekhono lokukhwabanisa elingu-10% ngaphezulu kunele-uric acid.

② IMIYALELO

I-5-10mg iyunithi ngayinye yomuntu omdala kanye nama-2-3 amayunithi wokudla okuqhubekayo kubalulekile ekudleni kwakho kwansuku zonke.

Ukufakwa kuhlu kubhalwe kanjena:

Izingane (iminyaka emi-3 kuya kwe-11) ≤l 0 mg / usuku
Ubusha (iminyaka eyi-11-21） ≤30 mg / usuku
Abantu abadala (iminyaka engama-21-80) ≤30 mg / usuku
