Protein: dab tsi thiab yog vim li cas muaj ib lub cev?

Ob peb cov neeg xav hais tias txhua txhua hnub hais txog dab tsi raws nraim noj thiab yuav ua li cas zoo tshaj plaws los tsim kom tau koj cov zaub mov. Tu siab, hais txog kev noj haus feem ntau xav tias tib neeg nrog loj noj qab haus huv tej teeb meem. Sawv daws yeej paub hais tias cov khoom noj yuav tsum tau protein. Yuav ua li cas yog no substance?

tsis yooj yim zog

Cov nqaijrog (cov nqaijrog) - ib tug loj heev macromolecules lub neej, uas tej zaum yuav muaj xws li ib tug plurality ntawm circuits. Tus me tshaj blocks uas los tsim kom tau cov zoo kawg li vaj tse - amino acids. Cov no hais tias, raws li cov kev cai ntawm rov tshwm sim, tag nrho molecules ua heev zog, yuav tsis raug txo mus rau lub thaj chaw ntawm cov amino acids. Cov nab npawb ntawm cov kev khiav dej num ua los ntawm cov nqaijrog nyob rau hauv tib neeg lub cev, yog incalculable, txawm hais tias ib tug pab pawg neeg ntawm kev khiav dej num yog tseem cais.

Thiab yog hais tias koj ua yuam kev?

Yog li, lub protein? Yuav ua li cas yog nws yog thiab yuav ua li cas ib hom yog txawv los ntawm lwm yam? Txawv cov nqi ntawm cov protein thiab cov amino acid ib theem zuj zus. Thiab ib tug me me ua haujlwm - thiab protein molecules yuav tsis ua lawv muaj nuj nqi. Tej zaum cov kev tshuaj ntsuam genetic code creeps nyob rau hauv kev ua yuam kev, thiab lub cuab yeej ntawm tus cai amino acids yog hloov nrog tsis ncaj ncees lawm - yog loj kab mob xws li myasthenia Heavy kev los yog sickle cell anemia. Nws yog ib qho tseem ceeb heev rau lub cev protein. Yuav ua li cas yog cov kev tshuaj ntsuam genetic mob muaj feem xyuam rau nws cov qauv? Qhov no yog kev tsis pom nrias thiab mob loj nyob rau theem ntawm tag nrho cov kab mob.

catalysis mechanism

Lom macromolecules ntawm cov nqaijrog yog tshwj xeeb yog ib qho tseem ceeb rau cov tib neeg vim hais tias ntawm lawv cov catalytic kev ua si. Feem ntau ntawm cov dab nyob rau hauv peb lub cev muaj peev xwm tsis muab qhov chaw tsis muaj qhov kev ua, vim hais tias cov tshuaj tsis muaj peev xwm pib nthawv vim lub zog yog vim li cas. Yog vim li cas yog protein? Yuav ua li cas yog nws seboy yog nyob rau hauv relation mus catalysis? Tej zaum koj yuav zoo li paub tswvyim, synonymous nrog "enzyme". Nws communicates nrog lub Cheebtsam ntawm cov tshuaj tiv thaiv active cov ntsiab lus, uas cov tshuaj tiv thaiv yuav pib, thiab ces yam xyuam xim "cia mus" os. Yog li, nws tswj pib ntawm cov tshuaj tiv thaiv, tab sis nws tus kheej yog tsis ntim rau hauv nws, raws li tau zoo raws li lwm yam catalyst.

Lub hauv paus ntawm lub zog

Heev tseem ceeb ntxwv muaj nuj nqi. Cov nqaijrog yog yuav luag ntshiab daim ntawv nyob rau hauv cov nqaij. Cov nqaij, uas muaj ntau yam noj nyob rau hauv thiaj li yuav tau cov nqaijrog - yog cov nqaij ntawm cov tsiaj. Txawm tias qhov zoo tshaj plaws cov nqaijrog - yog crushed (nyob rau hauv ib tug protein co). Nqaij yog tseem haum zoo absorbed. Zuj zus teeb meem nrog rau qhov no, kua khoom thiab legumes. Muaj ib tug ntau ntawm cov protein ntau, tab sis tshem tawm nws los ntawm cov khoom hloov tawm mus rau yuav tsis yooj yim rau lub cev.

Thaum lub me theem

Cov nqaijrog lub hauv paus ntawm lub hlwb, hu ua lub cytoskeleton, uas muab puab. Ib qho tseem ceeb protein muab kev koom tes nyob rau hauv lub thauj ntawm feem ntau yam yog tsis muaj peev xwm ntawm nws tus kheej mus los ntawm lub cell daim nyias nyias. Nyob rau theem ntawm lub cell nws yog nqa tawm twb hais catalytic kev ua si.

Uas cov nqaijrog yog zoo tshaj plaws rau noj? Feeb xam tau tias yog ib qho tseem ceeb cov tsiaj, tab sis tej zaum lawv yuav zoo yuav hloov nrog kua, Yog hais tias qhov no nroj twb pre-kho zoo heev. Piv txwv li, protein hmoov ua los ntawm cov kua muaj tiav protein thiab nqis zoo nqaij cov nqaij. Yog vim li cas cov zaub protein yog zoo dua rau koj noj qab haus huv? Nws tsis yog txuam nrog ib tug ntau ntawm cov roj thiab pab tsim cov roj cholesterol.
