Coenzymes yog cov organic sib txuas yooj yim uas cuam tshuam nrog cov enzymes los pab catalyze tshua. Lub enzyme muaj qhov chaw nquag nyob qhov twg nws catalyzes cov tshuaj tiv thaiv ntawm cov substrate, tab sis coenzyme khi rau lwm qhov chaw ntawm lub enzyme, hloov nws cov duab thiab pab nws ua lub luag haujlwm zoo dua rau nws cov haujlwm. Los ntawm cov tshuaj fab kis coenzyme A belongs rau cov thiol pawg. Qhov no txhais tau tias nws muaj cov leej faj thiab hydrogen.
Xwv Aen yog qhov tseem ceeb coenzyme. Lub cev tsim tawm nws thiab tsis tuaj yeem nyob yog tsis muaj nws. Coenzyme A tswj kev ntau dua 100 tshuaj lom neeg. Coenzyme A tau txiav txim siab los ua tus pabcuam ncau, cov tshuaj uas yuav tsum muaj los ua kom muaj qee yam enzymes thiab cov protein lossis tshuaj lom neeg cov tshuaj tiv thaiv tseem ceeb.
Raws li qee cov kws tshaj lij, coenzyme A yog tus pabcuam pabcuam cov roj ntsha uas ua kom yooj yim ntawm cov hlau oxidation. Cov txheej txheem no ua rau kev tsim cov tshuaj acetyl coenzyme A - ib yam tshuaj tseem ceeb uas tau siv los ua cov roj ntsha hauv lub cev nyob. Yog tsis muaj cov txheej txheem tseem ceeb no, yuav tsis muaj kev tsim cov khoom siv roj (cov kev sib txuas uas ua kom muaj kev ncaj ncees ntawm cov cell membrane - ib txheej tiv thaiv ntawm txhua lub cell).
Xwv Aen yog tsim hauv cov qe ntshav hauv lub siab thiab lwm qhov khoom nruab nrog cev tseem ceeb. Qhov siab tshaj plaws ntawm nws yog hauv lub plawv, raum, hlwb, qog adrenal thiab cov leeg pob txha.
Kev tso cai ntawm coenzyme A
Ntau txoj kev tshawb fawb txog kev tshawb fawb pom tias muaj coenzyme A yog qhov "enzyme tseem ceeb" - qhov tseeb nws yog qhov enzyme nquag tshaj plaws hauv cov metabolism hauv cov txheej txheem hauv lub cev. Coenzyme A yog ib qho tseem ceeb heev uas tsim nyog rau kev siv coenzyme Q rau kev tsim cov enzymes metabolic. Tsis tas li ntawd, nws ntseeg tau tias ua lub luag haujlwm tseem ceeb hauv lub cev kev paub los tiv thaiv kev ntxhov siab thiab ua kom lub cev tsis muaj zog.
Ib qho ntawm cov haujlwm tseem ceeb ntawm coenzyme A yog los pib lub zog ntawm lub zog hauv lub cev, hu ua Krebs lub sijhawm, thaum lub sijhawm ntawd kwv yees li 90% ntawm lub zog ntawm lub cev tau tsim tawm. Coenzyme A yog qhov tseem ceeb rau kev tsim cov hydrocortisone, ib qho kev tiv thaiv kev ntxhov siab.
Cov txiaj ntsig ntawm Coenzyme A
Coenzyme A txo cov kev tsis zoo los ntawm kev ntxhov siab thiab txo qis kev laus. Raws li peb txhua tus paub, kev ntxhov siab yog lub luag haujlwm rau peb qhov tseem ceeb ntawm kev tuag nyob rau hauv xyoo tsis ntev los - mob qog noj ntshav, mob hlab ntsha tawg thiab plawv nres. Kev ntxhov siab ua rau lub cev tsis muaj zog tiv thaiv kab mob, ua rau lub cev tiv thaiv kev kis tus mob thiab lwm yam teeb meem. Txhawm rau tiv thaiv kev ntxhov siab, lub cev ua cov tshuaj hormones hu ua glucocorticoids. Ntau dhau kev sib cais txo cov peev txheej ntawm coenzyme A hauv lub cev.
Nws ua kom lub cev muaj zog ntawm lub cev tsis muaj zog thiab tseem ceeb heev rau kev tsim thiab kho pob txha mos thiab cov leeg txhaws. Xwv Aen kuj tseem ceeb heev rau kev txo cov kev ntxhov siab vim tias, raws li tau hais los, nws tsim cov tshuaj los tiv thaiv kev ntxhov siab.
Coenzyme A yog qhov tseem ceeb heev rau cov neeg ncaws pob nquag vim nws muab cov zaub mov tseem ceeb rau lub cev xav tau los tso tawm lub zog anaerobic, uas yog qhov tseem ceeb thaum qoj ib ce.
Kuj tseem muaj xov xwm zoo rau cov poj niam uas muaj hnub nyoog. Nyob rau lub sijhawm no ntawm lub neej, txhua tus pojniam raug kev txom nyem los ntawm ntau yam kev hloov uas ua rau cov rog khaws, muaj kev nyuaj siab thiab ntxhov siab. Xwv Aen qhib cov nyiaj rog no thiab pab kom lawv hloov mus ua lub zog.
Coenzyme A tsis txaus
Qhov tsis muaj coenzyme A yog qhov tsis zoo rau lub cev. Nws tuaj yeem ua rau lub cev tsis muaj zog, kev ntxhov siab ntxiv thiab txhua qhov tshwm sim uas ob qhov xwm txheej tsis zoo no coj tuaj.
Qhov chaw ntawm coenzyme A
Tsis muaj cov khoom noj khoom haus ntawm coenzyme A tau pom. Lub cev lub cev tsim nws los ntawm peb lub ntsiab lus - adenosine triphosphate, cysteine thiab pantothenic acid (vitamin B5). Qhov zoo, txhua qhov ntawm peb qho no tuaj yeem muab tau los ntawm cov khoom noj los yog khoom noj khoom haus ntxiv.
Ntawm cov peev txheej tseem ceeb ntawm cov vitamin B5 yog qhob cij thiab brewer cov poov xab, nplooj siab, raum, cov khoom muaj lactic acid, txiv laum huab xeeb, cov hmoov nplej tag nrho, ceg tawv, oats, qaib cov txwv dub, ntsuab seem ntawm cov nroj tsuag. Lwm qhov chaw ntawm cov vitamins B5 yog ntses, nqaij, nqaij qaib, tseem muaj mov ci, noob nom noob tswv jelly.
