Kev Siv
Ergothioneine muaj cov ntawv thov dav dav thiab muaj kev cia siab rau kev lag luam hauv kev hloov pauv lub cev, kev khaws cia cell, tshuaj, khoom noj thiab dej haus, cov khoom noj ua haujlwm, pub tsiaj, tshuaj pleev ib ce thiab biotechnology.
Ua ib qho tshuaj antioxidant ntuj uas tsis muaj tshuaj lom nrog cov khoom cytoprotective muaj zog, nws tiv taus oxidation hauv cov kua dej. Vim li no, nws qhov concentration hauv qee cov nqaij tuaj yeem ncav cuag qib millimolar, thiab nws ua kom lub cev lub cev tiv thaiv antioxidant ntuj tsim.
Txawv ntawm ntau lwm yam tshuaj antioxidants, ergothioneine muaj peev xwm chelating cov hlau hnyav ions thiab tiv thaiv cov qe ntshav liab hauv lub cev los ntawm kev puas tsuaj los ntawm cov dawb radicals.
Ergothioneine yog ib qho tshuaj muaj zog uas tua tau hypochlorous acid (HOCl). Txawm hais tias muaj ntau yam tshuaj uas tuaj yeem ua rau hypochlorous acid tshwm sim, tab sis muaj ob peb yam uas ua tau sai npaum li ergothioneine.
Alpha-1-antiproteinase inhibitor (API), xws li elastase, muaj kev cuam tshuam loj heev rau hypochlorous acid. Ntawm qhov kev ntsuas ntawm lub cev, ergothioneine tuaj yeem tiv thaiv API tiv thaiv hypochlorous acid-induced inactivation. Vim tias neutrophils yog qhov tseem ceeb ntawm hypochlorous acid hauv tib neeg lub cev, ergothioneine pab tiv thaiv cov qe ntshav liab los ntawm kev puas tsuaj los ntawm neutrophils ntawm qhov chaw ua haujlwm ib txwm lossis cov qhov txhab o.
Ergothioneine (hu ua ET lossis EGT) yog ib qho amino acid derivative ntuj tsim uas tsis tshua muaj. Xyoo 1909, Charles Tanret tau rho tawm ib qho crystalline sulfur-muaj compound thaum kawm txog ergot fungi uas nyob hauv cov noob rye. Cov thiol uas yaj tau hauv dej no tom qab ntawd tau muab lub npe hu ua ergothioneine tom qab cov ergot fungi.
EGT pom muaj ntau hauv cov hlwb me me, cov nroj tsuag thiab cov tsiaj txhu, nrog rau cov khoom noj xws li nceb, taum dub, taum liab thiab oats. Raws li cov khoom endogenous hauv tib neeg lub cev, EGT sib sau ua ke ntawm cov concentration siab hauv ntau lub hlwb thiab cov nqaij, tshwj xeeb tshaj yog hauv cov qe ntshav liab, pob txha pob txha, siab, raum, phev, nrog rau lub lens thiab cornea ntawm lub qhov muag.
Qee cov kab mob me me suav nrog mycobacteria tuaj yeem tsim EGT, tab sis tib neeg lub cev tsis tuaj yeem tsim nws ntawm nws tus kheej thiab yuav tsum tau txais thiab khaws cia los ntawm kev noj zaub mov.
Hauv kev siv tshuaj lom neeg, ergothioneine yog ib qho derivative ntawm cov amino acids uas muaj sulfur. Nws cov sulfur atom ruaj khov yog vim nws muaj peev xwm ua antioxidant tshwj xeeb. Cov sulfur atom ntes thiab neutralizes free radicals, yog li txo qhov kev ntxhov siab oxidative thiab kev puas tsuaj rau cov cell. Tsis tas li ntawd, ergothioneine yog lipophilic, ua rau nws nkag mus rau hauv cov cell membranes thiab ua rau muaj cov teebmeem hauv cov cell, uas ua rau nws cov kev ua antioxidant zoo dua.
Ergothioneine tsis tshua muaj nyob rau hauv xwm. Dhau li ntawm cov nceb ergot, cov nyiaj me me kuj tseem tuaj yeem pom hauv qee lwm cov nceb, cov kab mob thiab cov nroj tsuag. Txawm li cas los xij, tib neeg feem ntau tau txais nws los ntawm cov khoom noj txhua hnub, suav nrog cov khoom xyaw xws li cov nceb oyster kub, ganoderma lucidum thiab cordyceps.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
