Protein yog cov khoom siv ntawm lub neej, tsis muaj protein ntau tsis muaj txoj sia.

Protein yog cov khoom siv hauv lub neej, tsis muaj protein ntau tsis muaj lub neej. Yog li ntawd nws yog ib yam khoom uas txuas nrog rau lub neej thiab rau txhua hom kev ua neej. Txhua lub cell thiab tag nrho cov khoom tseem ceeb hauv lub cev muaj cov protein koom nrog. Protein suav txog 16% ~ 20 feem pua ​​​​ntawm tib neeg lub cev qhov hnyav, uas yog, tus neeg laus 60kg muaj txog 9.6 ~ 12kg ntawm cov protein hauv nws lub cev, thiab cov protein muaj txog li 80 feem pua ​​ntawm cov khoom qhuav ntxiv rau dej.
1. Nws yog ib qho tseem ceeb ntawm tib neeg lub cev
Txhua lub cev ntawm tib neeg lub cev muaj cov protein, tshwj tsis yog qee lub cev tseem ceeb, txawm tias cov plaub hau, rau tes, thiab cov pob txha muaj protein "duab ntxoov ntxoo". Cov leeg muaj li 32 feem pua ​​-40 feem pua ​​ntawm lub cev qhov hnyav, thiab cov leeg tseem ceeb yog cov protein. Tsis tas li ntawd, lub paj hlwb kuj tseem ceeb heev rau cov protein ntxiv, tshwj xeeb tshaj yog rau cov menyuam yaus. Protein yog cov khoom siv hauv paus ntawm tag nrho lub neej, ib feem tseem ceeb ntawm lub cev hlwb, thiab cov khoom siv tseem ceeb rau kev rov ua dua tshiab thiab kho tib neeg cov ntaub so ntswg. Txhua cov ntaub so ntswg ntawm tib neeg lub cev: plaub hau, tawv nqaij, nqaij, pob txha, cov kab mob hauv nruab nrog cev, hlwb, ntshav, paj hlwb, endocrine, thiab lwm yam yog tsim los ntawm cov protein, yog li kev noj haus tsim tus neeg nws tus kheej. Protein tseem ceeb heev rau tib neeg txoj kev loj hlob thiab kev loj hlob.
2. Tswj lub cev ua haujlwm ntawm tib neeg lub cev
Proteins muaj ntau yam tseem ceeb cov tshuaj hormones thiab digestive enzymes, pab heredity, ua digestive enzymes, tswj osmotic siab thiab tswj tib neeg lub cev tsis muaj zog.
3. Cov khoom tsim nyog rau kev thauj neeg lub cev
Protein ua lub luag haujlwm tseem ceeb hauv kev tswj cov metabolism hauv lub cev thiab thauj ntau yam khoom hauv lub cev. Carrier proteins yog qhov tseem ceeb rau kev tswj hwm kev ua neej nyob hauv tib neeg lub cev. Nws tuaj yeem nqa ntau yam khoom hauv lub cev. Piv txwv li, hemoglobin - thauj oxygen, lipoprotein - thauj cov rog, receptors ntawm cell membranes, thiab transporters.
4. Ntxiv lub zog ntawm tib neeg lub cev
Protein yog ib qho ntawm peb cov khoom siv hluav taws xob loj, txawm tias nws tsis ua lub luag haujlwm tseem ceeb ntawm lub zog, tab sis nws muaj lub luag haujlwm tseem ceeb. Hauv cov xeev tshwj xeeb xws li kev tshaib kev nqhis thiab kab mob, tib neeg lub cev yuav muab lub zog ntau dua los ntawm kev rhuav tshem cov protein. Cov khoom noj muaj protein ntau thiab nws cov teebmeem kev noj qab haus huv. Cov khoom noj uas muaj protein ntau txhua hnub ntawm cov protein muaj xws li tsiaj cov zaub mov thiab cov zaub mov cog. Cov khoom noj tsiaj feem ntau suav nrog ntau yam nqaij, qe, thiab mis nyuj.
