Amaphrotheni: yini futhi kungani kukhona umzimba?

Bambalwa abantu abacabanga nsuku zonke ngalokho ncamashi ukudla nendlela engcono kakhulu yokwakha ekudleni kwakho. Ngeshwa, ngokudla ngokuvamile ukuthi abantu kuphela izinkinga zempilo ezingathí sina. Wonke umuntu uyazi ukuthi ekudleni kufanele kube amaprotheni. Kuyini lokhu izidakamizwa?

izakhiwo ngingakhululeki

Amaphrotheni (amaprotheni) - a macromolecules giant ukuphila, okungase aqukethe sebuningini izifunda. Amabhulokhi kulencane kuyiphi ukwakha lezi wakha izakhiwo ezinkulu ezibabazekayo - amino acid. Umphumela uba ukuthi, ngokomthetho ka ukuvela, amangqamuzana omoya wonke abe izakhiwo eziyinkimbinkimbi kakhulu, ayikwazi ukwenziwa sezindawo amino acid. Isibalo nemisebenzi eyenziwa namaprotheni emzimbeni womuntu, mkhulu kakhulu, nakuba iqembu imisebenzi namanje ekhishwe inyumbazane.

Futhi uma wenza iphutha?

Ngakho, amaprotheni? Kuyini ke nokuthi uhlobo olulodwa lihlukile kwezinye? amanani angalingani amaprotheni nama-amino acid ukulandelana. Futhi omunye shift encane - namaprotheni molecule asisakwazi ukwenza umsebenzi wabo. Ngezinye izikhathi isimiso sezakhi zofuzo aqala ngephutha, futhi impahla esephepheni amino acid kufakwe okungalungile - kukhona izifo ezibucayi ezifana myasthenia gravis noma isikela cell anemia. Kubalulekile kakhulu amaprotheni zomzimba. Yiziphi izifo ezibangelwa ufuzo ezihlobene oyiyo? Lokhu akunakugwenywa futhi sina zokugula ezingeni wonke umzimba.

catalysis indlela

macromolecules eziphilayo amaprotheni kubalulekile ikakhulukazi abantu ngenxa yomsebenzi wabo okhanda amanye amathuba. Iningi izinqubo emzimbeni wethu angeke kwenteke ngaphandle lo msebenzi, ngoba kuvamile ayikwazanga ukuqala ngokuzenzekelayo ngenxa yezizathu amandla. Kungani amaprotheni? Kuyini seboy kuhlobene catalysis? Wena kungase kubonakale umqondo uzobajayela, lahlotshaniswa nokuba "enzyme". It baxhumana izingxenye ukusabela amaphuzu asebenzayo, okuvumela ukuphendula ukuqala, bese ngokuphepha "uyayekela" Izinto. Ngakho, kwenza kubelula ukuthi ekuqaleni ukusabela, kodwa ngokwalo kudliwe ke, kanye nanoma yimuphi omunye kulethe.

Ngesisekelo ukunyakaza

umsebenzi kwesakhiwo ebaluleke kakhulu. Amaphrotheni kukhona ifomu cishe okumsulwa ezitholakala imisipha. Inyama, okuyinto abaningi badle ukuze bathole amaprotheni - iyona imisipha kwezilwane. Nakuba okungcono amaprotheni - uchotshoziwe (e Shake amaprotheni). Inyama nayo ugxile kahle. isimo sibe sibi nalokhu, imikhiqizo soy nokuyimidumba. Kukhona amaningi, kodwa kokuyikhipha umkhiqizo kuvela kube nzima umzimba.

Ezingeni ezincane

Amaphrotheni yisisekelo cell, elibizwa ngokuthi ama-cytoskeleton, onikeza ukuma. Enye amaprotheni ebalulekile ukuthuthwa izinto kakhulu abakwazi ngokuzimela zidlule ulwelwesi cell. Ezingeni iseli ke Kwenziwa sekushiwo umsebenzi okhanda amanye amathuba.

Yikuphi amaprotheni kukhona okungcono? Ngokwesiko kubhekwe izilwane ezibalulekile, kodwa kungenzeka kahle esikhundleni soy, uma lesi sitshalo babe pre-baphathwe kahle impela. Ngokwesibonelo, amaprotheni izimpushana wenza kusukela soy aqukethe amaprotheni ephelele futhi kugaywe kwemisipha inyama kangcono. Kungani amaprotheni zemifino kungcono ngoba kuthinta impilo yakho? It is hhayi ezihlobene eningi fat kanti iyasiza nasekwenzeni cholesterol.
