Acetylcholinesterase catalyzes kev tawg ntawm acetylcholine tshuaj molecules ib zaug kev sib txuas lus ntawm cov cell yog tiav. Qhov no yog ib txoj haujlwm tseem ceeb. Sib xyaw zoo li Sarin thiab VX cov kab mob paj hlwb, uas txwv qhov kev ua ntawm Cov tshuaj acetylcholinesterase , yog lom heev, thiab ua rau tuag taus txawm tias me me.
Ua li no, lub hom phiaj ntawm acetylcholinesterase yog dab tsi?
Acetylcholinesterase (HGNC cim ACHE; EC 3.1. 1.7), tseem hu ua AChE lossis acetylhydrolase, yog thawj cov tshuaj cholinesterase hauv lub cev. Nws yog ib qho enzyme uas txhawb kev tawg ntawm acetylcholine thiab qee qhov lwm cov choline esters uas muaj nuj nqi raws li neurotransmitters.
Kuj Paub, dab tsi ua rau acetylcholinesterase? Presynaptic vesicles tso tawm acetylcholine tshuaj mus rau hauv qhov chaw sib dhos uas nws khi rau nws tus txais. Txoj cai ib sab ntawm tus txais yog Cov tshuaj acetylcholinesterase , cov enzyme uas tawg acetylcholine tshuaj hauv acetate thiab choline. Qhov chaw anionic ua haujlwm los khi ib qho molecule ntawm ACh rau cov enzyme.
Xav txog qhov no, yuav muaj dab tsi tshwm sim yam tsis muaj acetylcholinesterase?
Lub xub ntiag ntawm cov tshuaj cholinesterase inhibiting tshuaj tiv thaiv kev tawg ntawm acetylcholine tshuaj . Acetylcholine tuaj yeem txhim kho, ua rau "jam" hauv lub paj hlwb. Yog acetylcholinesterase tshuaj tsis muaj peev xwm tawg lossis tshem tawm acetylcholine tshuaj , cov leeg tuaj yeem txuas ntxiv mus yam tsis tuaj yeem tswj tau.
Acetylcholinesterase inhibitor ua dab tsi?
Ib acetylcholinesterase inhibitor (AChEI) yog tus inhibitor uas inhibits acetylcholinesterase tshuaj los ntawm kev rhuav tshem acetylcholine mus rau hauv choline thiab acetate, yog li ua rau ob qho tib si qib thiab sijhawm ntawm kev ua ntawm cov neurotransmitter acetylcholine hauv lub hauv paus paj hlwb, tsis siv neeg ganglia thiab neuromuscular

Vim li cas peb thiaj xav tau cov rooj zaum?
Qhov tseem ceeb ntawm lub rooj zaum tsim qauv uas txhawb nqa qis dua. Kev ua ntawm zaum tuaj yeem tso ntau qhov kev ntxhov siab ntawm lub cev. Lub cev noj qab nyob zoo - thaum tus txha nqaj qaum ua kom haum -txhawb nqa kev nplij siab ntau dua, suav nrog txhim kho kev mloog zoo thiab ua siab ntev dhau los ntawm cov sijhawm ua haujlwm zaum zaum ntev
Vim li cas peb xav tau cov poov tshuaj hauv peb lub hlwb?
Potassium yog ib qho tseem ceeb ntawm cov zaub mov hauv lub cev. Nws pab tswj cov kua dej sib npaug, cov leeg nqaij thiab cov paj hlwb. Dab tsi ntxiv, kev noj zaub mov muaj poov tshuaj ntau yuav pab txo cov ntshav siab thiab khaws dej, tiv thaiv mob stroke thiab tiv thaiv pob txha thiab pob zeb hauv raum
Vim li cas peb thiaj xav tau cov ntshav xa mus thoob lub cev?
Cov ntshav muab koj lub cev nrog cov pa oxygen thiab cov as -ham uas nws xav tau. Nws tseem nqa cov pov tseg. Koj lub siab zoo li lub twj tso kua mis, lossis ob lub twj tso kua mis hauv ib qho. Sab xis ntawm koj lub siab tau txais cov ntshav los ntawm lub cev thiab tso nws mus rau lub ntsws
Vim li cas peb thiaj xav tau cov leeg?
Cov leeg: Vim li cas lawv thiaj tseem ceeb? Cov leeg thiab cov hlab ntsha tso cai rau peb txav peb lub cev. Lawv ua kom peb lub cev sab hauv ua haujlwm. Tib neeg lub cev muaj ntau dua 600 cov leeg, uas muaj li ntawm 40 feem pua ntawm peb lub cev hnyav
Vim li cas peb thiaj xav tau txoj kev ua pa?
Lub tshuab ua pa ua ob yam tseem ceeb heev: nws nqa cov pa oxygen nkag rau hauv peb lub cev, uas peb xav tau rau peb cov cell nyob thiab ua haujlwm kom raug; thiab nws pab peb tshem tawm cov pa roj carbon dioxide, uas yog cov khoom pov tseg ntawm kev ua haujlwm ntawm tes
