Qhov tsawg ntawm cov protein yog qhov tsawg kawg nkaus ntawm cov protein uas pab tswj tuav nitrogen equilibrium hauv lub cev (nitrogen yog lub hauv paus tseem ceeb rau txhua yam nyob, raws li nws yog ib feem ntawm tag nrho cov amino acids thiab proteins). Nws tau pom tias thaum lub sijhawm yoo mov rau 8-10 hnub ntawm ib qho khoom noj tas li ntawm lub cev - kwv yees li 23.2 grams (rau ib tug neeg nrog ib pawg ntawm 70 kg). Txawm li cas los xij, qhov no tsis txhais tau hais tias qhov tsawg ntawm cov protein ntau ntawm cov zaub mov yuav txaus siab rau cov kev xav tau ntawm peb lub cev rau hauv qhov feem ntawm kev noj haus, tshwj xeeb tshaj yog thaum ua kev ua kis las. Qhov tsawg kawg nkaus ntawm cov protein no tsuas yog tswj tau cov kev ua haujlwm ntawm tus neeg mob lub cev, thiab txawm tias lub sijhawm luv luv.
Qhov zoo tshaj plaws ntawm protein ntau yog cov protein ntau hauv cov zaub mov uas txaus siab rau tib neeg cov kev xav tau rau nitrogen tebchaw thiab yog li muab cov khoom tsim nyog rau cov leeg uas rov qab kho tom qab, ua haujlwm kom muaj kev ua haujlwm ntawm cov kabmob, pabcuam kev tsim kom muaj kev tivthaiv rau kev kis kabmob. Qhov zoo tshaj plaws rau tus kabmob ntawm tus poj niam uas muaj hnub nyoog li ntawm 90 - 100 grams protein ib hnub, thiab nrog cov kev ua si ntau heev, qhov no tuaj yeem ua tau - nce mus txog 130-140 grams ib hnub thiab ntau dua. Nws ntseeg hais tias ua kom muaj protein ntau zoo ib hnub twg thaum ua lub cev qoj ib ce rau lub cev qhov hnyav, qhov nruab nrab ntawm 1.5 gram protein thiab ntau dua. Txawm li cas los xij, txawm tias muaj kev cob qhia tshaj plaws hauv kev ua si, tus nqi ntawm cov protein tsis pub tshaj 2 mus rau 2.5 gram ib kilogram ntawm lub cev qhov hnyav. Yog tias koj tuaj koom nrog kev ua kis las los yog qoj qws nrog lub hom phiaj ntawm kev noj qab haus huv, ces cov ntsiab lus ntawm cov khoom noj uas koj pom tau yuav tsum tau muab xam tias nws npaum li cas, uas ua rau kom noj tau li ntawm 1.5 mus rau 1.7 grams ntawm cov hnyuv ntawm lub cev qhov hnyav.
Txawm li cas los xij, ua raws li cov protein tsawg thiab cov protein zoo nyob hauv kev ua kis las tsis yog tib qho kev tsim nyog rau kev noj zaub mov txaus, uas muab cov txheej txheem rov qab los hauv lub cev tom qab kawm kev cob qhia. Qhov tseeb yog tias cov khoom noj muaj peev xwm ua tau txawv hauv lawv cov zaub mov noj. Piv txwv li, cov nqaij ntawm cov tsiaj txhu yog qhov zoo tshaj plaws rau tib neeg lub cev hais txog lawv cov kab mob amino acid. Lawv muaj tag nrho cov tseem ceeb amino acids uas tsim nyog rau kev loj hlob thiab ceev nrawm ntawm cov leeg nqaij ntawm cov kev ua si. Cov khoom noj muaj nyob rau hauv cov khoom noj cog qoob loo muaj tsawg heev ntawm qee yam tseem ceeb hauv cov amino acids lossis cov cim los ntawm tag nrho cov tsis tuaj yeem. Yog li, thaum xyaum ntaus kev ua si, kev noj zaub mov noj yuav yog nqaij thiab khoom noj siv mis, qe thiab ntses.
Yog li, vim qhov noj tau cov txiaj ntsig ntawm cov protein tsawg thiab cov protein kom zoo, ib tug yuav tsum sim muab koj lub cev nrog cov khoom uas tsis tshua tsim nyog rau kev ua si.
