Yuav kom nyob siab, tswj kev tiv thaiv, tsim cov hlwb thiab muab cov txheej txheem metabolic, peb lub cev tsis tu ncua yuav tsum muaj cov amino acids. Qhov ntau lub zog lub cev siv, ntau amino acids nws xav tau. Lub cev coj mus kuaj cov amino acids thiab txais lawv nrog zaub mov. Txawm li cas los xij, ntau dua qhov khaus, xws li kev ua kis las, yuav tsum muaj ib qho tseem ceeb ntawm cov amino acids, nyob rau hauv daim ntawv ua kua rau kev txhim kho zoo.
Nyob hauv cov xwm txheej, muaj ntau tshaj 20 cov amino acids uas tau cais raws li ntau yam ntxwv. Qhov feem ntau paub yog kev cais ntawm cov amino acids rau interchangeable thiab irreplaceable.
Hloov cov amino acids
Xws li cov amino acids, uas yog ib feem ntawm cov proteins, nkag mus rau lub cev nrog zaub mov thiab tso tawm thaum lub sij hawm nws cleavage. Ntawm lawv peb muaj peev xwm paub qhov txawv:
- Alanine yog ib feem ntawm cov ntaub so ntswg uas ua rau lub cev tiv thaiv kab mob uas tswj cov ntshav qab zib;
- glycine - yog ib feem ntawm hemoglobin, tswj cov txheej txheem metabolic, muaj cov nyhuv calming, siv tshuaj;
- Glutamine yog ib qho ntawm cov amino acids uas feem ntau, koom rau hauv kev ua haujlwm ntawm lub cev tsis muaj zog, cuam tshuam loj hlob ntawm cov nqaij pob txha, stimulates hlwb ua si thiab txhawb zog nco;
- proline - muab kev koom tes hauv kev tsim cov ntaub so ntswg thiab nqaij leeg;
- serine - txhawb kev tiv thaiv, stimulates nco, koom hauv cov metabolism hauv fatty acids;
- taurine - yog kev koom tes hauv kev nqus thiab kev faib cov rog, txo cov roj cholesterol;
- cystine - txhawb nqa kev tsim cov ntaub so ntswg, txo qhov mob, tseem ceeb heev rau cov rau tes thiab plaub hau.
Lub synthesis ntawm hloov cov amino acids tshwm sim nyob rau hauv lub cev thaum txoj kev protein protein cleavage. Txawm li cas los, lub peculiarity ntawm no hom amino acids yog tias cov kab mob muaj peev xwm tsim tau lawv los ntawm lwm cov amino acids, yog li synthesizing cov twb muaj tebchaw.
Qhov tseem ceeb ntawm cov amino acids
Lawv raug hu ua li no, vim hais tias lub cev tsis tuaj yeem tsim cov amino acids ntawm nws tus kheej. Tsis zoo li cov amino acids uas tau hloov, uas lub cev muaj peev xwm tsim tau los ntawm lwm cov amino acids, lub irreplaceable tuaj rau hauv lub cev tshwj xeeb tshaj tawm sab nraud. Ntawm lawv:
- histidine - siv los kho tshuaj anemia thiab cov tshuaj tiv thaiv kab mob, muaj kev koom tes hauv cov qe ntshav dawb thiab ntshav dawb;
- isoleucine - ib qho tseem ceeb ntawm cov amino acid hauv zus tau los ntawm hemoglobin, muab cov nqaij mob thiab pab tiv thaiv nrog kev ua haujlwm dhau;
- leucine - heals, txhawb nqa kev loj hlob sai ntawm pob txha, tiv thaiv kev rhuav tshem ntawm cov protein;
- methionine - restores daim siab thiab mob lub raum, txo cov roj cholesterol;
- lysine - accelerates lub synthesis protein, ua tau collagen, thiab ua ke nrog cov vitamin C cov ntaub ntawv L-carnitine - lub caij ua lub luag haujlwm ntawm lub zog hauv cov leeg thiab siv oxygen.
Nyob rau hauv qhov tseeb, lub protein molecule nws tus kheej muaj cov amino acids thiab tsis absorbed los ntawm lub cev nyob rau hauv nws daim ntawv dawb huv. Thaum cov protein nkag rau hauv lub cev, nws muab faib rau hauv cov khoom thiab sib sau ua ke cov amino acids tsim nyog los ua kom lub cev tseem ceeb ntawm lub cev.
