Kawm paub cov ntsiab cai zais cia hauv kev tsim lub cev uas yuav pab txhim kho kev nqus cov zaub mov muaj protein thiab ua kom cov protein sib txuas. Histidine yog cov amino acid sib xyaw siv los ntawm lub cev feem ntau rau kev sib xyaw ntawm histamine, ntau yam enzymes, thiab protein ntau. Nco tseg tias tam sim no, cov kws tshawb fawb tseem tsis tuaj yeem tsim cov pab pawg twg ntawm amines Histidine koom nrog - hloov pauv lossis hloov tsis tau.
Feem ntau cov kws kuaj ntshav biochemists zoo li xav txog amine uas tsis tuaj yeem hloov pauv tau. Kev tsis muaj peev xwm ntawm cov khoom hauv cov phiaj xwm kev noj zaub mov tuaj yeem ua rau txo qis hauv nws cov concentration hauv lub cev. Nyob rau tib lub sijhawm, lwm pab pawg ntawm cov kws tshawb fawb cais Histidine raws li qhov tsis tuaj yeem hloov pauv tau, vim tias amine yog ib feem ntawm qee cov protein sib txuas.
Histidine ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem biochemical. Yog li, cia peb hais tias cov khoom no muaj peev xwm tiv thaiv glutamine synthesis. Cov tshuaj no yog cov tshuaj txhawb rau kev tsim cov glutamine thiab koom nrog hauv cov metabolism hauv nitrogen thiab ammonia. Yog li, peb tuaj yeem hais tau zoo tias Histidine tuaj yeem thaiv qhov tawg ntawm cov protein sib txuas thiab ua rau qeeb cov tshuaj nitrogen tsim tawm hauv cov txheej txheem ntawm tes ntawm cov nqaij. Hauv chav kawm ntawm ib qho ntawm kev sim, nws tau pom tias kev tsim cov amine tsis muaj peev xwm ua rau qeeb hauv cov metabolism hauv cov protein sib txuas.
Carnosine yog dipeptide pom hauv ntau cov ntaub so ntswg. Cov kws tshawb fawb tau pom tias cov khoom muaj peev xwm ua kom qeeb cov txheej txheem kev laus vim tias muaj cov tshuaj tiv thaiv kab mob ua ntej. Carnosine tseem cuam tshuam rau tus nqi ntawm myocardial contraction, uas yog qhov pom tau zoo tshaj plaws hauv qhov tsis muaj oxygen. Tsis tas li, cov tshuaj muaj peev xwm so cov phab ntsa ntawm cov hlab ntshav.
Kev siv histidine thiab carnosine hauv kev tsim lub cev
Ntxiv rau qhov tseeb uas tau hais los saum no, cov kws tshawb fawb qhia tias cov tshuaj no muaj peev xwm cuam tshuam rau kev qhia hloov kho. Txij li Histidine cuam tshuam rau tus nqi ntawm kev sib tawg ntawm cov protein sib xyaw, nws muaj feem ntau tias nws yuav tuaj yeem ua rau qeeb cov tshuaj tiv thaiv catabolic pom thaum ua haujlwm nyuaj.
Tam sim no, qhov no tseem yog txoj kev xav, thiab tsis muaj pov thawj tshawb fawb txog qhov cuam tshuam rau lub cev. Txawm li cas los xij, hauv kev xav, kev siv Histidine tuaj yeem txo qis keeb kwm yav dhau los. Ib qho ntxiv, nyob rau hauv lub xeev ntawm kev tawm dag zog hauv cov ntshav ntawm cov kis las, qis qis ntawm albumin thiab hemoglobin feem ntau pom, thiab hauv cov ntxhais kuj muaj hlau. Tej zaum, siv Histidine nws yuav tuaj yeem tshem tawm qhov teeb meem no.
Txij li Carnosine ua raws li cov txheej txheem zom zaub mov tsis zoo, nws yuav tuaj yeem txo qis acidity hauv cov leeg nqaij thaum ua haujlwm hnyav. Raws li qhov tshwm sim, cov kis las yuav tsum nce lawv lub siab ntev thiab tuaj yeem txhim kho qhov kev kawm tau zoo. Ib qho ntxiv, nws muaj peev xwm nce qhov nrawm ntawm kev rov zoo ntawm cov teeb tsa. Cov kws tshawb fawb tseem qhia tias carnosine yuav tuaj yeem khaws cov leeg nqaij thaum ua kis las ncaws pob. Txawm li cas los xij, peb rov hais dua tias txhua qhov tseeb no tseem tsis tau muaj pov thawj tshawb fawb thiab xav tau kev pov thawj ntxiv.
Histidine thiab Carnosine zoo li cas?
Txhawm rau txiav txim siab lub peev xwm ntawm ib yam khoom cuam tshuam rau tus nqi ntawm cov txheej txheem metabolic, cov kws tshawb fawb txiav txim siab nws muaj nyob hauv lub cev. Peb twb tau hais los saud tias Carnosine nrog Histidine tseem cuam tshuam lawv cov ntsiab lus hauv cov leeg nqaij. Piv txwv li, thaum sim nrog nas, kev nce qib ntawm carnosine hauv cov leeg nqaij tau pom nrog kev siv carnosine niaj hnub los ntawm tsiaj. Qhov siab ntawm cov tshuaj no tau nce 5 zaug. Kuj tseem muaj kev nce qib ob zaug hauv qib ntawm histidine.
Hauv qhov kev sim zaum thib ob, nees dawb tau muab 100 milligrams ntawm alanine thiab 12.5 milligrams ntawm histidine txhua hnub. Qhov kev sim tau siv sijhawm ib hlis, thiab nyob rau lub sijhawm no tau nce qhov kev mloog zoo ntawm carnosine hauv cov hlwb ntawm cov leeg nqaij.
Tib lub sijhawm, nws tseem nyuaj hais raws nraim li cas kev siv Carnosine thiab Histidine tuaj yeem cuam tshuam rau cov kis las ncaws pob kev ua kis las. Kev sib raug zoo tau pom ntawm qhov tsis muaj zog, qib ntawm cov tshuaj histidine zoo li hauv cov leeg thiab qhov feem pua ntawm cov nqaij nrawm hauv cov tsiaj nyob hauv kev cuam tshuam ntawm kev tawm dag zog cardio. Qhov no tau muab cov kws tshawb fawb qhov laj thawj los xav tias kev nce qib ntawm cov khoom zoo li histidine yog lub hauv paus tseem ceeb hauv cov leeg nqaij thaum ua haujlwm cardio.
Txog tam sim no, tsuas yog ib qho kev sim tib neeg tau ua nyob rau hauv uas cov kws tshawb fawb tau sim tsim kom muaj kev sib raug zoo ntawm qib carnosine hauv cov leeg thiab cov txiaj ntsig ntawm kev ua kom muaj kev kawm siab (tsheb kauj vab nyob ruaj ruaj). Txoj kev tshawb no koom nrog kaum ib tus txiv neej. Cov txiaj ntsig ntawm kev sim muab qhov laj thawj los xav tias kev nce qib ntawm cov carnosine hauv cov leeg tuaj yeem txhim kho cov txiaj ntsig ntawm kev cob qhia thiab nce kev ua haujlwm kom nrawm dua. Tab sis qhov kev xav no tseem yuav tsum tau lees paub.
