Kev Siv
Qhov hnyav molecular ntawm glutathione yog 307.33, nrog rau qhov chaw yaj ntawm 189-193 ℃ (kev lwj). Cov siv lead ua tsis muaj xim, pob tshab, nyias thiab columnar, thiab qhov chaw isoelectric yog 5.93. Nws yaj tau hauv dej, dilute cawv, kua ammonia thiab methylformamide, tab sis tsis yaj hauv cawv, ether thiab acetone. Tsuas yog GSH muaj kev ua haujlwm ntawm lub cev hauv cov kab mob, thaum GSSG yuav tsum tau txo ua ntej nws tuaj yeem ua nws cov haujlwm tseem ceeb ntawm lub cev. GSH tsis yooj yim rau kev khaws cia hauv qab dej ua haujlwm siab. Tsuas yog los ntawm kev tswj cov dej ua haujlwm hauv qab 0.3 nws tuaj yeem khaws cia ruaj khov rau lub sijhawm ntev. Cov kev tshawb fawb tau qhia tias hauv cov kua vitamin C aqueous uas muaj GSH (pH3.3), vim muaj cov txiaj ntsig txo qis ntawm vitamin C, GSH hauv cov tshuaj yuav tsis raug oxidized rau GSSG, tab sis nws qhov kev lwj sai dua. GSSG uas muaj nyob hauv cov kua vitamin C aqueous yuav tsis hloov mus ua GSH thiab muaj kev ruaj khov zoo. Ntxiv mus, GSSG uas noj tau hauv qhov ncauj tuaj yeem txo qis mus rau GSH nyob rau sab saud ntawm txoj hnyuv me. Nws raug nqus rau ntawm qhov chaw ntawm cov hlwb epithelial me me los ntawm kev ua haujlwm ntawm γ-GTP (uas rhuav tshem GSH mus rau hauv glutamic acid thiab Cys-Gly) thiab dipeptidase, thiab kuj tseem tuaj yeem ua nws cov haujlwm tseem ceeb ntawm lub cev.
Glutathione txo qis yog ib qho peptide me me uas muaj ntau nyob rau hauv cov kab mob muaj sia, tshwj xeeb tshaj yog nyob rau hauv cov hlwb siab. Nws muaj cov haujlwm ntawm kev tiv thaiv lub hlwb siab, txhawb kev ua haujlwm ntawm cov enzymes siab, thiab sib xyaw nrog ntau yam tshuaj lom kom ua lub luag haujlwm tshem tawm cov tshuaj lom. Nws muaj cov txiaj ntsig zoo heev rau kev kho mob rau kev raug mob siab los ntawm ntau yam xws li kev lom tshuaj thiab kev lom cawv, nrog rau cov kab mob xws li mob siab cirrhosis.
Nws muaj cov haujlwm xws li antioxidation, free radical scavenging, detoxification, txhim kho kev tiv thaiv kab mob, ncua kev laus, tiv thaiv mob qog noj ntshav thiab tiv thaiv kev puas tsuaj ntawm hluav taws xob.
Glutathione siv tau ua cov tshuaj biochemical reagent thiab antidote, feem ntau yog rau kev kho mob lom los ntawm cov hlau hnyav, acrylonitrile, fluorides, carbon monoxide thiab cov organic solvents, thiab lwm yam.
Cov tshuaj antioxidants endogenous uas ua lub luag haujlwm tseem ceeb hauv kev txo cov reactive oxygen hom tsim thaum lub sijhawm cellular metabolism thiab kev ua pa sai sai. Glutathione -S-transferase catalyzes qhov tsim ntawm glutathione sulfide nrog heteroorganisms, leukotrienes thiab lwm yam molecules nrog electrophilic chaw. Glutathione kuj tsim disulfide bonds nrog cysteine residues hauv cov protein. Los ntawm cov txheej txheem no, nws tuaj yeem muaj cov nyhuv txawv txawv ntawm kev txo qis cov txiaj ntsig ntawm cov neeg sawv cev tiv thaiv kab mob qog noj ntshav.
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.
