Dawb radicals Tsis yog tsuas yog tsim nyob rau hauv peb lub cev lub cev thaum lub sij hawm homeostasis tab sis kuj los ntawm kev raug rau sab nraud qhov chaw xws li ib puag ncig muaj kuab paug, tshuaj lom hlau, luam yeeb, thiab tshuaj tua kab, uas ntxiv kev puas tsuaj rau peb lub cev lub nra ntawm oxidative kev nyuaj siab.
Hauv qhov no, dab tsi ua rau tsim cov dawb radicals?
Oxidative stress tshwm sim thaum cov pa molecule sib cais rau hauv ib qho atoms nrog unpaired electrons, uas yog hu ua dawb radicals . Electrons nyiam ua khub, yog li cov atoms, hu ua dawb radicals , scavenge lub cev mus nrhiav lwm yam electrons kom lawv tuaj yeem ua khub. Qhov no ua rau kev puas tsuaj rau cov hlwb, cov protein thiab DNA.
Qhov thib ob, cov piv txwv ntawm cov dawb radicals yog dab tsi? Ib qho piv txwv tseem ceeb ntawm cov dawb radical yog hydroxyl radical (HO•), molecule uas yog ib qho hydrogen atom luv ntawm cov dej molecule thiab yog li muaj ib daim ntawv cog lus "dangling" los ntawm cov pa oxygen.
Kuj tseem yuav paub, cov zaub mov twg ua rau dawb radicals?
Tsis txhob muaj glycemic siab zaub mov , los yog zaub mov uas yog nplua nuj nyob rau hauv refined carbohydrates thiab qab zib. Lawv feem ntau yuav tsim dawb radicals . Txwv cov nqaij ua tiav xws li hnyuv ntxwm, nqaij npuas kib thiab salami. Lawv muaj preservatives, uas ua rau zus tau tej cov dawb radicals.
Dab tsi yog cov yam ntxwv ntawm cov dawb radicals?
A dawb radical tuaj yeem txhais tau tias yog ib qho atom lossis molecule uas muaj ib lossis ntau dua cov khoom siv hluav taws xob tsis sib xws hauv valency plhaub lossis sab nrauv thiab muaj peev xwm ntawm kev ywj pheej. Tus lej khib ntawm electron(s) ntawm a dawb radical ua rau nws tsis ruaj khov, luv luv nyob thiab muaj zog heev.

Tsis tas li ntawd lub tsev kawm ntawv ua lub luag haujlwm tseem ceeb hauv ib puag ncig ntawm tus kheej. Hauv tsev kawm ntawv tus menyuam tau ntsib nrog cov phooj ywg thiab cov kws qhia ntawv uas nws tus cwj pwm tuaj yeem cuam tshuam
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?

Dab tsi ib puag ncig yam cuam tshuam rau kev loj hlob microbial?
Muaj ntau yam ntawm ib puag ncig uas cuam tshuam rau kev loj hlob ntawm microbial. Lub cev tseem ceeb tshaj plaws yog pH, kub, oxygen, siab, thiab salinity. pH ntsuas seb acidic los yog yooj yim (alkaline) cov tshuaj yog li cas, thiab microbes yuav loj hlob nyob rau hauv acidic, yooj yim, los yog nruab nrab pH
