Protein yog ib pawg ntawm cov khoom tsim nyog rau lub neej ntawm txhua yam kabmob. Qhov tseeb yog hais tias nws cov molecules ua tau ib tug loj tus naj npawb ntawm ntau haiv neeg functions, yam uas tsis muaj lub hav zoov ntawm tej yam nyob rau hauv yuav ua tsis tau.
Y Yuav ua li cas yog proteins?
Txhua yam khoom muaj xws li cov khoom me me hu ua amino acids. Nyob rau hauv tag nrho, tsuas yog 40 ntawm lawv tau pom, tib lub sijhawm, tsuas yog 20 ntawm lawv tuaj yeem pom hauv tib neeg lub cev.
Amino acids tuaj yeem ua ke hauv yuav luag txhua qhov kev txiav txim. Ib qho kev hloov pauv hauv txoj haujlwm tsawg kawg 1 ntawm lawv yuav ua tiav metamorphosis ntawm cov khoom uas cov protein yuav muaj. Raws li qhov tshwm sim, niaj hnub no muaj ntau ntau yam ntawm cov proteins.
YKev ua haujlwm ntawm cov protein molecules
Tam sim no, nws tau tsim tias cov proteins ua lub luag haujlwm tshwj xeeb rau txhua yam muaj sia. Qhov tseeb yog tias cov protein yog cov khoom siv roj ntsha uas tuaj yeem cuam tshuam rau txhua qhov ntawm lub cev. Lawm, cov protein sib txawv yog lub luag haujlwm rau ntau qhov chaw ntawm lub cev.
Yog tias peb tham txog kev ua haujlwm ntawm cov protein, ces ua ntej ntawm tag nrho nws yuav tsum tau nco ntsoov qhov tseeb tias lawvCov khoom tseem ceeb tshaj plaws ntawm lub cev - enzymes thiab cov tshuaj hormones. Lawv tswj cov tib neeg cov metabolism hauv txhua qib. Cov proteins hauv qab no yog cov piv txwv zoo heev: pepsin, chymotrypsin, somatotropin, vasopressin, insulin, prolactin thiab lwm yam.
Ntxiv rau, nws yuav tsum tau muab sau tseg tias cov leeg nqaij fibers yog tsim los ntawm cov proteins. Vim muaj cov khoom tshwj xeeb ntawm actin thiab myosin, tib neeg, nrog rau txhua yam tsiaj, muaj peev xwm txav mus los. Qhov tseeb yog tias lawv tuaj yeem cog lus thiab so. Yog li ntawd, nyob rau hauv kev tswj ntawm lub hauv paus paj hlwb, cov leeg nqaij fibers muab kev txav. Yog li ntawd, cov protein yog cov khoom uas tso cai rau tib neeg thiab lwm yam tsiaj txhu txav mus los.
Tsis tas li, qee zaum, cov proteins tuaj yeem siv los ua lub zog. Txawm li cas los xij, qhov no tsuas yog tshwm sim thaum tsis txaus ntawm cov carbohydrates thiab cov rog nkag mus rau hauv lub cev. Yog li, peb tuaj yeem hais nrog kev ntseeg siab tias cov proteins yog cov khoom uas, txawm hais tias lawv tuaj yeem siv los ua cov khoom siv hluav taws xob, lawv tsis tau npaj rau qhov no.
cov ntsiab lus ntawm ntau yam khoom noj
Txhawm rau kom muaj sia nyob, tus neeg xav tau kev noj cov protein ntau li 100 g ib hnub. Nws ntseeg tau tias feem ntau cov protein tuaj yeem tau los ntawm cov nqaij. Qhov tseeb, tej yam txawv me ntsis. Feem ntau cov proteins muaj nyob rau hauv caviar ntawm chum salmon thiab sturgeon. Tsis tas li ntawd, muaj ntau cov proteins muaj nyob rau hauv cov kua txiv hmab txiv ntoo qhuav porcini nceb, taum, lentils thiab peas.
Txawm li cas los xij, rau tib neegprotein yog cov khoom uas tau txais los ntawm cov nqaij, nqaij qaib, thiab ntses. Cov khoom noj uas muaj protein ntau yog tuna, nqaij nyuj, nqaij qaib, nqaij npuas, luav, qaib ntxhw, thiab nqaij npua.
Swiss thiab Dutch cheese yog qhov tseem ceeb ntawm cov protein. Lwm cov khoom ua los ntawm cov mis nyuj muaj protein tsawg heev.
Ntau tus neeg xav paub ntau npaum li cas cov protein nyob hauv qe. Nws yog tam sim no paub tias lawv qhuav residue muaj ntau cov proteins. Raws li cov qe zoo tib yam, muaj cov protein tsawg dua ntawm cov nqaij.
