Proteins yog ib qho tseem ceeb ntawm txhua txoj kev ua raws roj ntsha uas tshwm sim hauv lub cev. Lawv koom nrog kev tsim cov enzymes tsim nyog rau kev tsim tsev. Proteins thauj cov khoom noj thiab oxygen rau cov nruab nrog cev thiab cov ntaub so ntswg. Qhov tseem ceeb cov amino acids, uas tau tsim los ntawm kev ua kom cov protein tsis txaus, koom nrog cov txheej txheem hauv metabolic, hauv kev tsim kho cell thiab hauv cov synthesis ntawm hemoglobin.
Protein cov ntsiab lus hauv cov nqaij
Cov zaub mov sib txawv muaj cov protein sib txawv. Cov protein ntau ua tiav yog pom hauv nqaij nyug, lawv cov nyiaj yog 25%. Lawv muaj tag nrho cov tseem ceeb thiab tsis tseem ceeb cov amino acids uas lub cev xav tau. Lub cev assimilates veal yooj yim dua, nws kuj muaj protein ntau (txog 20%). Npua cov nqaij, piv rau nqaij nyug, muaj cov ntaub so ntswg tsis sib kis, yog li nws muaj kev sib tw ntau dua li nqaij nyug thiab nqaij mos. Protein hauv nqaij npuas - 14% mus rau 19%. Cov menyuam yaj ua tawv dua li nqaij nyug, nws muaj cov hlau tsawg, potassium, thiab ntsev phosphorus. Tus nqi ntawm cov protein nyob rau hauv yaj yog 20%. Luav nqaij yog cov khoom noj muaj txiaj ntsig zoo tshaj plaws. Nws muaj cov ntsiab lus ncaj ncees ntawm cov protein (21%), B vitamins, hlau.
Offal tsis muaj tsawg tshaj li nqaij. Txij li thaum lawv muaj cov zaub mov ntau, hlau, vitamins, lawv pom zoo rau cov neeg muaj ntshav tsis txaus.
Cov ntsiab lus protein nyob hauv nqaij qaib thiab ntses
Tsis zoo li nqaij nyug, nqaij qaib muaj cov protein ua tiav thiab yooj yim zom nrog cov feem ntau lees paub amino acid rau lub cev. Nqaij qaib nqaij muaj qhov tsim nyog los ua ke ntawm cov ntxhia thiab vitamins. Cov ntses protein muaj tag nrho cov amino acids tseem ceeb rau lub cev. Tsis zoo li cov nqaij cov nqaij, cov ntses protein muaj qhov tseem ceeb amino acid methionine, lawv muaj cov ntaub so ntswg me me, uas sawv cev los ntawm collagen, uas yooj yim hloov mus rau hauv nws cov soluble form - gelatin.
Cov ntses protein tau zoo dua los ntawm lub cev - los ntawm 93-98% (cov nqaijrog nqaij - los ntawm 87-89%). Tus nqi ntawm cov protein nyob hauv ntses nyob ntawm tus tsiaj. Qhov nruab nrab, nws yog 16%. Cov roj ntses muaj cov roj ntau ntawm cov zaub mov muaj roj polyunsaturated fatty acids. Ntses ntses noj ntses yog ib yam khoom noj muaj txiaj ntsig heev. Nws muaj los ntawm 30% protein thiab nce txog 15% cov rog (txog 15%), cov rog-thiab dej-soluble vitamins, phosphorus, potassium. Cov ntses luam yeeb thiab noj ntsev yog cov zaub mov muaj txiaj ntsig tsawg dua. Cov protein nyob hauv nws ntau zuj zus zom thiab nqus tau.
Cov kaus poom ntses tsis muaj ntau tus naj npawb ntawm cov txiaj ntsig zoo, txij li cov khoom noj khoom haus tau muab pov tseg thaum lub sij hawm npaj cov kaus poom zaub mov.
Cov protein nyob hauv cov qe thiab cov khoom noj siv mis
Cov protein ntau tshaj plaws, ua tiav los ntawm lub cev, yog pom hauv cov qe qe. Qe dawb muaj qhov pom ntawm cov amino acids tseem ceeb, nws muaj cov tshuaj uas zoo tom qab kho cua sov. Tab sis cov qe nyoos dawb yog qhov tsis zoo vim tias muaj nyob rau hauv nws ntawm cov sib txuas uas txwv qhov kev txiav txim ntawm cov enzymes uas tsim nyog rau kev zom zaub mov.
Kuj tseem muaj protein nyob hauv cov khoom noj mis nyuj. Lawv cov nyiaj hauv ib qho khoom lag luam tshwj xeeb yog txawv: hauv mis, txog 5% protein, hauv cheese txog 22%. Cov khoom noj mis nyuj muaj cov casein, uas yog nqus tau los ntawm lub cev ntev, yog li cov kws qhia zaub mov xav kom siv thaum yav tsaus ntuj. Rau cov tib neeg saib lawv qhov hnyav, nws yog qhov zoo dua los xaiv skim mis thiab tsev cheese rau kev noj haus, vim tias cheese muaj roj ntau ntawm cov rog. Nws yog ib qho tseem ceeb kom tswj cov qib protein ntau hauv lub cev thoob plaws hnub, yog li nws zoo dua rau kev noj zaub mov kom tsawg thiab tsawg.
