Kev noj cov protein hauv kev noj zaub mov txhawb cov leeg protein sib txuas. Rau qhov sib txawv ntawm cov protein, cov txiaj ntsig ntawm cov leeg ua ke sib txawv heev. Feem coob ntawm qhov sib txawv no hauv cov txiaj ntsig ntawm cov protein protein synthesis nyob hauv kev siv tom qab siv ntawmcov amino acids tseem ceeb(tshwj xeeb tshaj yog leucine). Kev siv cov amino acids tseem ceeb tom qab noj mov tau tswj hwm los ntawm ntau cov txheej txheem hauv lub cev, suav nrog kev zom zaub mov protein, kev nqus cov amino acid, visceral amino acid khaws cia thiab pob txha pob txha perfusion, nrog rau ntau yam kev noj haus, suav nrog cov amino acid muaj pes tsawg leeg, cov ntsiab lus amino acid tseem ceeb thiab lub xub ntiag ntawm kev tiv thaiv kev noj zaub mov zoo.
Hauv txoj kev tshawb fawb no, peb txheeb xyuas ntau yam kev cog qoob loo sib cais (oats, lupins, nplej, hemp, microalgae, taum pauv, mov xim av, peas, pob kws thiab qos yaj ywm), tsiaj cais cov protein (whey, mis nyuj, caseinate), Casein thiab qe) thiab tib neeg skeletal nqaij protein. Siv ultra-high performance kua chromatography-tandem mass spectrometry (UPLC-MS/MS) thev naus laus zis, peb ntsuas cov amino acid muaj pes tsawg leeg ntawm cov hom protein no thiab cov khoom siv. Qhov kev tshawb fawb no muab lub hauv paus rau kev txheeb xyuas cov protein-based cog nrog lub peev xwm anabolic siab thiab txiav txim siab cov cog cog cog tshiab uas muab cov txiaj ntsig zoo ntawm cov amino acids zoo ib yam rau feem ntau cov tsiaj protein.
Cov txiaj ntsig sim:
1) Sib piv cov ntsiab lus protein
Piv nrog cov ntsiab lus protein ntawm tib tus tsiaj thiab cog cov protein sib cais, cov ntsiab lus ntawm cov zaub protein yog 51%-81%, ntawm cov noob hemp (51%), lupine (61%), pob kws (65%), cov ntsiab lus yog qis dua; protein xim av xim av (79%), protein pea (80%), qos yaj ywm protein (80%), nplej protein (81%), cov ntsiab lus yog qhov siab. Cov ntsiab lus ntawm cov tsiaj protein yog 51% txog 81%. Tib neeg cov leeg pob txha qhuav muaj 84% cov protein. Cov protein cov ntsiab lus ntawm kev kuaj los ntawm cov neeg muab khoom sib txawv kuj txawv. Kev faib cov protein ntau yog hom twg los ntawm 74 txog 88%, cov kua protein muaj li ntawm 61%txog 91%, cov protein pea muaj li ntawm 77 txog 81%, cov protein pob kws muaj li ntawm 58 txog 75%, thiab cov protein ntau li ntawm 77 txog 77%. 83%, whey protein los ntawm 72 txog 84%, casein los ntawm 67 txog 78%.
2) Sib piv cov ntsiab lus amino acid tseem ceeb
Piv nrog cov tsiaj protein (suav txog 37 % thiab 38 % ntawm tag nrho cov protein) thiab tib neeg cov leeg nqaij cov leeg nqaij (suav txog 38 % ntawm tag nrho cov protein), qhov tseem ceeb amino acid cov ntsiab lus ntawm cov nroj tsuag protein (suav txog 26 | ^| +-2 % ntawm tag nrho cov protein) Qis. Nroj-based protein oats (21 %), lupins (21 %), hom qoob mog (22 %), hemp (23 %) thiab microalgae (23 %) muaj cov ntsiab lus tseem ceeb amino acid qis dua LEEJ TWG/FAO/UNU amino acids Thov (WHO/FAO/UNU Kws Tshaj Lij Muab Tswv Yim, 2007). Thaum ib qho ntawm cov protein yog qhov tsuas yog siv cov protein, nws tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov amino acids tseem ceeb. Thov nco ntsoov tias qhov kev xav tau no yog ua raws cov lus pom zoo txhua hnub rau cov neeg laus ntawm 0.66 g/kg. Cov nroj tsuag raws cov protein uas ua tau raws li qhov xav tau amino acid xav tau suav nrog taum pauv (27 %), mov xim av (28 %), taum pauv (30 %), pob kws (32 %), thiab qos yaj ywm (37 | ^|) Ib. Ntawm cov tsiaj protein, cov protein whey muaj qhov tseem ceeb tshaj plaws cov amino acid cov ntsiab lus, nce mus txog 43 %. Mis protein (39 %) thiab calcium caseinate (38 %) qhia cov khoom nruab nrab, thaum casein (34 %) thiab qe (32 %) muaj qis dua cov ntsiab lus amino acid.
Hauv kev xaus, peb pom qhov ntawd tiag
Neeg tsis noj nqaij protein tsis txhais tau tias ib qho ntawm cov amino acids tseem ceeb uas ploj lawm. Nws tsuas yog qhov sib piv ntawm 8 cov amino acids ntawm cov protein ib leeg tsis noj zaub tsis zoo ib yam li qhov sib piv haum rau kev nqus los ntawm peb tib neeg lub cev (txheeb ze rau cov tsiaj protein).
Txawm li cas los xij, kev noj zaub mov tsis tau txhais tau tias yog kev koom ua ke ntawm cov protein. Thaum peb ntxiv cov protein nrog cov protein sib xyaw ua ke, qhov no dhau los ua teeb meem ua ke. Nws yuav tsum muaj peev xwm siv qee qhov sib xyaw ua ke los tsim cov protein ntau uas tuaj yeem phim lub cev' kev nqus. Nws kuj tseem tuaj yeem nyob ze rau qhov xav tau ntawm tib neeg lub cev ntau dua li peb ib leeg ntawm cov tsiaj protein.
