Txhua lub xov tooj ntawm tib neeg lub cev yog qhov tshwj xeeb. Thiab tus kheej no yog muab los ntawm cov proteins. Cov proteins yog dab tsi? Lawv kuj hu ua proteins. Lawv yog cov champions nyob rau hauv complexity ntawm cov molecules uas ua rau cov proteins nws tus kheej. Tshwj xeeb tshaj yog cov protein ntau hauv cov plaub hau, tawv nqaij, pob txha, rau tes thiab cov leeg nqaij. Tab sis tsis yog tag nrho, cov proteins yog ib feem ntawm cov tshuaj hormones, neurotransmitters, tshuaj tiv thaiv kab mob, enzymes, thiab cov pa oxygen hu ua hemoglobin. Peb tshuav 20% ntawm peb lub cev hnyav, yog li nws tseem ceeb heev kom tau txais cov khoom siv hauv tsev txaus los ntawm zaub mov.
Cov ntsiab lus ntawm tag nrho
Raws li cov lus ua los ntawm cov ntawv, cov proteins yog tsim los ntawm cov amino acids. Muaj 20 "cov tsiaj ntawv" nyob rau hauv cov tsiaj ntawv ntawm tib neeg biochemistry. Txuas ntxiv qhov piv txwv, txawm li cas los xij, nws tsim nyog sau cia tias "cov lus" lawv tus kheej muaj ntau lab ntawm "cov ntawv". Xws li complexity txhais tau hais tias ib tug loj heev vulnerability ntawm lub system. Yog li ntawd, cov amino acid muaj pes tsawg leeg tseem ceeb heev.cov proteins uas koj noj. Tsis muaj cov khoom txaus - thiab cov molecules yuav tsis tuaj yeem sib sau ua ke. Los yog lub cev yuav tau ua kom puas lwm yam molecules. Piv txwv li, thaum yoo mov, cov amino acids raug coj los ntawm cov ntshav thiab cov pob txha.
Txhua tus muaj nws tus kheej
Dab tsi yog cov protein thiab vim li cas lawv thiaj li txawv? Cov no yog kev sib txuas ntawm cov qauv kev sib txuas, txuas nrog yam tsawg kawg ntawm peb theem (qee zaum kuj muaj cov proteins quaternary). Thiab lawv yog tshwj xeeb vim hais tias lub cev synthesizes lawv raws li cov ntaub ntawv caj ces embedded nyob rau hauv DNA ntawm peb txhua tus. Txhua lub xovtooj ntawm tes muaj nws tus kheej "khoom siv" rau kev tsim cov protein - lub ribosomal complex. Txawm li cas los xij, cov menyuam ntxaib, uas yog cov noob qoob loo, muaj cov proteins tib yam, uas ua rau lawv zoo tagnrho pub rau ib leeg.
Yuav tsum muaj cov amino acids
Vim cov proteins yog tus kheej, lub cev tsis nqus lawv tag nrho. Nyob rau hauv lub digestive system, cov proteins tau tawg mus rau hauv cov amino acids thiab absorbed nyob rau hauv daim ntawv no. Thiab tom qab ntawd lub cev xa lawv mus rau qhov chaw uas yuav tsum tau "kho ua haujlwm". Lawv xav tau txhua hnub nyob rau hauv ntau qhov ntawm daim tawv nqaij, hauv ob sab phlu ntawm lub plab hnyuv thiab nyob rau hauv cov cheeb tsam loj hlob ntawm tes thiab plaub hau. Hauv luv luv, tsis quav ntsej cov khoom noj kom raug yog qhov txaus ntshai rau kev noj qab haus huv.
Problems of veganism
Yuav ua li cas yog cov proteins ntawm cov khoom noj muaj txiaj ntsig? Yav dhau los, muaj kev xav tias cov amino acids ntawm cov zaub protein tsis tuaj yeem yog cov khoom siv hauv tsev, vim lawv tsis nqus tsis tau qee cov amino acids uas yog tsiaj cov ntaub so ntswg. Cov lus no, thaum kuaj, tau dhau los ua lus dab neeg. Thaum twgdigestion tshwm sim nyob rau hauv lub plab, amino acids ntawm tag nrho cov hom yog tso rau hauv cov zaub mov bolus. Yog li, tag nrho 20 nyob rau hauv txoj cai proportions nkag mus rau hauv cov hnyuv. Thiab txhua yam yog zoo kawg nkaus digestible. Txawm hais tias ua ib tug vegan yeej tsis zoo, vim muaj qee cov vitamins thiab yam tseem ceeb uas tsis yog synthesized hauv "herbivorous" neeg.
Cov Txheej Txheem Txheej Txheem
Cov protein nyob hauv tib neeg lub cev ua lub luag haujlwm tseem ceeb hauv kev tswj hwm, ob qho tib si ntxhov siab thiab lom zem. Neurotransmitters yog cov khoom uas xa cov impulses ntawm ib tug neuron mus rau lwm tus. Thiab kev tswj hwm kev lom zem nrog kev pab ntawm cov protein yog muab los ntawm kev sib txuas ntawm cov tshuaj hormones, uas maj mam tab sis muaj tseeb coj cov txheej txheem hauv lub cev.
Zoo kawg
proteins yog dab tsi? Cov no yog cov khoom ntawm peb lub cev, tus kheej thiab tsis tshua muaj kev nyuaj. Muaj nees nkaum amino acids thiab tsim los rau kev tiv thaiv (lub cev tiv thaiv kab mob proteins), kev tswj hwm thiab kev ua haujlwm tsim nyog.
