Cov amino acids tseem ceeb: Cov no yog cov amino acids uas tib neeg lub cev (los yog lwm yam vertebrates) tsis tuaj yeem ua ke autonomously los yog nws cov synthesis yog deb ntawm lub cev qhov kev xav tau thiab yuav tsum tau muab los ntawm cov khoom noj sab nraud. Qhov xav tau ntawm cov amino acids tseem ceeb rau cov neeg laus yog li 20% mus rau 37% ntawm cov protein xav tau. Muaj 8 hom, thiab lawv cov haujlwm yog raws li hauv qab no:
Lysine: Txhawb lub hlwb kev loj hlob, yog ib feem ntawm lub siab thiab lub gallbladder, txhawb kev rog metabolism, tswj lub caj pas pineal, mammary caj pas, corpus luteum thiab zes qe menyuam, thiab tiv thaiv cell degeneration;
Tryptophan: Txhawb kev tsim cov kua txiv hmab txiv ntoo thiab kua txiv pancreatic;
Phenylalanine: Koom tes hauv kev tshem tawm qhov poob ntawm lub raum thiab zais zis ua haujlwm;
Methionine: koom nrog hauv cov hemoglobin, cov ntaub so ntswg thiab cov ntshav, thiab muaj kev ua haujlwm ntawm kev txhawb nqa tus po, pancreas thiab lymph;
Threonine: Muaj kev ua haujlwm ntawm kev hloov qee cov amino acids kom ua tiav qhov sib npaug;
Isoleucine: koom nrog kev tswj hwm thiab cov metabolism hauv thymus, spleen thiab pituitary caj pas;
Leucine: Ntsuas isoleucine;
Valine: Ua rau lub cev luteum, qog mammary thiab zes qe menyuam. Semi- qhov tseem ceeb thiab cov amino acids tseem ceeb: Amino acids uas tib neeg lub cev tuaj yeem tsim tau tab sis feem ntau tsis tuaj yeem ua tau raws li cov kev xav tau ib txwm hu ua semi- qhov tseem ceeb lossis cov amino acids tseem ceeb. Cov no feem ntau yog arginine thiab histidine, uas yog cov amino acids tseem ceeb hauv kev loj hlob thaum yau. Tib neeg lub cev xav tau cov amino acids tseem ceeb txo qis thaum muaj hnub nyoog, nrog kev txo qis hauv cov neeg laus piv rau cov menyuam mos. Lawv lub luag haujlwm yog raws li nram no:
Arginine: Arginine thiab deoxycholic acid compound npaj (minoxaline) yog cov tshuaj zoo rau kev kho mob syphilis, kab mob jaundice, thiab lwm yam.
Histidine: tuaj yeem siv los ua biochemical reagent thiab kws tshuaj, thiab tseem siv tau rau hauv kev kho mob plawv, ntshav ntshav, mob caj dab, thiab lwm yam.
Tsis yog -cov amino acids tseem ceeb: Cov no yog cov amino acids uas tib neeg (los yog lwm yam vertebrates) tuaj yeem ua ke los ntawm cov neeg ua ntej yooj yim thiab tsis tas yuav tau txais los ntawm cov khoom noj. Piv txwv li glycine thiab alanine.
