Ergothionein (mercapto histidine trimethyl internal ntsev)
Ergothionine(EGT) yog lub ntuj antioxidant uas tuaj yeem tiv thaiv cov hlwb hauv tib neeg lub cev thiab yog ib qho tseem ceeb hauv lub cev.
Hauv kev kho tawv nqaij, ergotamine muaj zog antioxidant zog. Nws tuaj yeem cuam tshuam cov dawb radicals, txo oxidative kev puas tsuaj, tiv thaiv cov tawv nqaij hlwb los ntawm ib puag ncig ib puag ncig, pab ncua kev laus ntawm daim tawv nqaij, thiab tswj cov tawv nqaij elasticity thiab radiance.
Ntxiv rau thaj chaw ntawm kev tu tawv nqaij, ergotamine kuj muaj cov ntawv thov hauv kev lag luam tshuaj. Piv txwv li, nyob rau hauv kev tsim kho ntawm qee cov tshuaj, nws tuaj yeem siv los ua cov khoom siv pabcuam los pab txhim kho kev ruaj ntseg thiab kev ua tau zoo ntawm cov tshuaj. Hauv kev ua zaub mov, kuj tseem muaj kev tshawb fawb tshawb fawb txog qhov muaj peev xwm ntawm kev siv nws ua cov khoom noj ntxiv los txhim kho cov khoom noj antioxidant ntawm cov zaub mov thiab txuas ntxiv nws lub txee lub neej.
Ergothionein muaj kev nyab xeeb siab. Hauv cov khoom tu tawv nqaij, qhov concentration ntawm additives feem ntau txawv nyob ntawm tus qauv thiab kev ua tau zoo ntawm cov khoom, feem ntau yog li ntawm 0.1% mus rau 5%.
Lub luag haujlwm tseem ceeb
Antioxidant
Ergothionein tuaj yeem hnov mob sai sai nrog cov dawb radicals los hloov lawv mus rau hauv cov khoom tsis zoo, thiab nws tsis yooj yim ploj. Nyob rau tib lub sijhawm, nws tuaj yeem tswj hwm qib ntawm lwm cov tshuaj antioxidants (xws liVC thiab glutathione), yog li tiv thaiv cov tawv nqaij ntawm oxidative puas.
Nws cov txheej txheem ntawm kev ua haujlwm yog kom tshem tawm tau zoo - OH (hydroxyl radicals), chelate divalent hlau ions 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, inhibit tooj liab ion nyob ntawm oxidation ntawm oxygenated hemoglobin, thiab tseem inhibit. Cov tshuaj tiv thaiv peroxidation uas txhawb nqa arachidonic acid tom qab myoglobin (los yog hemoglobin) yog tov nrog H2O2.
Antiinflammatory
Cov lus teb inflammatory nyob rau hauv lub cev yog ib qho kev tiv thaiv ntuj teb rau stimuli, nrog rau kev tshwm sim ntawm lub cev tiv thaiv kev puas tsuaj. Ergothionein tuaj yeem tiv thaiv kev tsim cov kab mob inflammatory, txo cov qib ntawm inflammatory teb, thiab txo cov tawv nqaij tsis xis nyob. Nws exerts anti-inflammatory teebmeem los ntawm regulating intracellular signaling pathways thiab inhibiting qhov kev qhia ntawm o ntawm cov noob caj noob ces. Piv txwv li, rau cov tawv nqaij rhiab lossis pob txuv, ergotamine tuaj yeem pab txo qhov mob thiab txhawb kev kho tawv nqaij.
Tiv thaiv kev yees duab
Ergothionein tuaj yeem tiv thaiv DNA cleavage los ntawm ultraviolet lub teeb thiab hydrogen peroxide, thiab tseem tuaj yeem tshem tawm cov dawb radicals thiab nqus cov hluav taws xob ultraviolet kom tshem tawm kev puas tsuaj rau DNA. Tsis pub dhau lub ultraviolet absorption ntau yam, ergothionein muaj qhov nqus nqus wavelength zoo ib yam li DNA. Yog li ntawd, ergothionein tuaj yeem ua lub cev lim dej rau ultraviolet hluav taws xob.
Tam sim no, ntau qhov kev tshawb fawb tau pom tias ergotamine yog cov khoom siv tshuaj pleev thaiv hnub zoo heev uas tuaj yeem tiv thaiv kev puas tsuaj rau daim tawv nqaij los ntawm UV hluav taws xob.
Txhawb kev tsim ntawm collagen protein
Ergothionein tuaj yeem txhawb kev nce ntawm cov fibroblasts thiab txhawb cov synthesis ntawm collagen thiab elastin. Nws txhawb txoj kev qhia ntawm collagen noob thiab protein synthesis los ntawm activating tej yam signaling molecules nyob rau hauv lub hlwb.
