Mosebetsi sireletsang liprotheine. Sebopeho le mosebetsi wa liprotheine

Liprotheine tse motheong oa phelang tsohle tse phelang. dintho tsena ke karolo ea lera la seleng, organelles, lefufuru, tendons le letlalo squamous derivatives. Leha ho le joalo, e le sireletsang mosebetsi liprotheine - e mong oa bohlokoa ka ho fetisisa.

Liprotheine: makgetheng mehaho

Hammoho le lipids, lik'habohaedreite le acid nucleic, liprotheine tse manyolo dintho tseo theha motheong oa libōpuoa phelang. Ba tsohle - biopolymers tlhaho. thepa tsena li entsoe ka repetitive diyuniti mehaho. Ba bitsoa monomers. Bakeng sa liprotheine joalo diyuniti mehaho di-amino acid. Tlameletsoe 'moho, ba ile ba theha molecule kgolo.

Maemo ea mokhatlo oa tlhaloganya sebaka sa protheine

Ketane, e bopilweng ka amino acid mashome a mabeli a ka theha dibopeho tse sa tšoaneng. Tsena ke maemo a ea mokhatlo oa tlhaloganya sebaka kapa conformation tsa protheine ena. Sebopeho sa mathomo e emeloang ke ketane ea-amino acid. Ha e se e sothehileng ka spiral e, ho na le se mahareng. Sebopeho e phahameng le hlaha ka sotha conformations fetileng ka bolo kapa globule. Empa sebopeho latelang tsa boima ka ho fetisisa - quaternary. Ho na le globules 'maloa.

thepa ea liprotheine

Ha mohaho o quaternary liha ho sa mathomo, e leng ho ka liketane tsa amino acid, joale ho na le tšebetso e bitsoang denaturation. Ho reversible. Letoto la-amino acid ea nang le bokhoni ea hape ho theha e sebopeho rarahaneng ho feta. Empa ha ho na le ke timetso, ke hore, timetso ea mathomo sebōpeho sa protheine le ho tsosolosa ke ke ha khoneha. Mokhoa ona ke ha etsolloa. Itseng timetsong atlehe, e mong le e sa rōna hantle, ha thermally sebetswa lihlahisoa entsoeng ka protheine - mahe, tlhapi, nama.

Mesebetsi ya liprotheine: tafole

Protein limolek'hule tse mnogobrazny haholo. Sena se etsa hore e mengata e fapaneng ka menyetla e, e leng ka lebaka la ho sebopeho amino acid e. Mesebetsi ya liprotheine (tafole e na le tlhahisoleseding tshwanelanang) ke boemo bo hlokahalang bakeng sa ho ba teng ha lintho tse phelang.

Mosebetsi sireletsang liprotheine le ka ntho e phelang

Joalokaha u ka bona, le mesebetsi ya liprotheine tse fapa-fapaneng haholo le ea bohlokoa ho bohlokoa tsa lona. Empa re se builoeng leha ho le joalo ka mong oa bona. Mosebetsi sireletsang liprotheine ka 'mele ke ho thibela ho kenella ka hare tsa dintho tsoang linaheng tse ling, e leng ho ka baka kotsi e bohlokoa ho' mele. Ha sena se etsahala, liprotheine tse khethehileng kgona ho kokobetsa ho tsona. basireletsi tsena li bitsoa lisireletsi kapa immunoglobulins.

Tshebetso ya ho eaba ba etsa maloetseng

Le mong le e mong phefumoloho ka 'mele ea rōna phunyeletse libaktheria le likokoana-hloko. Ba ba lokolloa ka maling, moo ba ileng ba qala ho ka mafolofolo li atile '. Leha ho le joalo, ka tsela eo ba ema e le tšitiso e khōlō. Sena protheine lero la mali - immunoglobulins kapa lisireletsi. Ba khethehileng 'me ba tšoauoa ka le matla a ho lemoha le ho kokobetsa ho dintho tsoang linaheng tse ling ho' mele le sebopeho. Ba bitsoa antigens. Kahoo bonahala mosebetsi sireletsang liprotheine le. Mehlala ya lona le ka bontšoa boitsebiso bo mabapi le interferon. protheine ena e boetse ke e inehetseng le e iphumanela ho likokoana-hloko. ntho ena ke esita le ka lebaka la bongata ba lithethefatsi immunostimulatory.

Ka lebaka la ho ba teng ha ho sireletsa protheine 'mele o khona ho hanela likaroloana pathogenic, i.e. o thehoa boitshireletso ba mmele. Ho ka ba congenital kapa se fumaneng. Pele tse phelang tsohle filoe tloha motsotso la tsoalo, 'me kahoo bophelo ba ka khona. A reka bonahala ka mor'a ntse mafu a sa tšoaneng a tšoaetsanoang.

tšireletso ea ho phetha molao feela

Liprotheine sebeletsa mosebetsi e sireletsang, ho thibela lisele ka ho toba le phelang khahlanong le tshusumetso phetha molao feela. Ka mohlala, exoskeleton tsa crustaceans khetla phetha karolo e itseng, ho tshepahala ho sireletsa litaba tse ka hare tsohle. Bone, lefufuru, mesifa le theha motheong ea 'mele,' me a sa feela ho thibela tshenyo lisele le bonolo 'me litho tsa ka hare, empa hape netefatsa mokhatlo oa lona ho sebaka.

clots mali

Tsela hoama - ke e boetse e le mosebetsi sireletsang liprotheine le. Ho ka etsahala ka lebaka la ho ba teng ha lisele tse khethehileng - liplatelete. Ha senyehile methapo ea mali di timetsoa. Ka lebaka leo, lero la mali qhibilihang ka har'a protheine fibrinogen e sokolohela foromo lona insoluble - fibrin. Sena ke e rarahaneng enzymatic thulaganyong, eo fibrin linaleli hangata e intertwine le theha marangrang le letšo-letšo leo ho thibela dutla ea mali. Ka mantsoe a mang, ho thehoa mali clot kapa thrombus. Sena ke hore a arabele sireletsang 'mele. Ha bophelo bo tloaelehileng ba tshebetso nka e lebetsoeng le ea metsotso e leshome. Empa lefu incoagulability mali - hemophilia, e ama haholo-holo banna, monna a ka 'na shoa esita le ntsa kotsi hanyenyane.

Leha ho le joalo, haeba clots mali ba thehoa ka hare ho sejana mali, ho ka ba kotsi haholo. Maemong a mang, e esita le ho etsa hore ho tlōla botšepehi ba hae le ho tsoa mali ka hare. Tabeng ena, ea lithethefatsi kgothaletswa, ho fapana le hoo, mali thinning.

lik'hemik'hale tšireletso ea

Mosebetsi sireletsang ea liprotheine bonahala ntoa e khahlanong le mahlahana pathogenic lik'hemik'hale. Le e qala ka molomo. Hang ka lona, reflex lijo bakang salivation. Motheong oa ntho ena ke metsi, potlakisang tsebetso ea lik'hemik'hale hore khomarela polysaccharides le lysozyme. Ke ntho ea ho qetela kokobetsa ho limolek'hule tse kotsi, ho sireletsa 'mele ho tloha kgahlamelo ya maqhubu a bona ka ho eketsehileng. Leng ho eona, le lera la mucous pampitšaneng ena gastrointestinal, 'me ka mokelikeli eohle, e leng bathes le cornea. Ka e ngata lysozyme e lebese, mucus, nasal le protheine mahe khoho.

Kahoo, mosebetsi sireletsang protheine e bonahatsa haholo-holo ka neutralizing baktheria le ea vaerase likaroloana maling a e phelang. Ka lebaka leo, o ile a theha le matla a ho hanela mahlahana lefu tse bakang. Le e bitsoa sireletsehile maloetseng ana. Liprotheine tse litho tsa Link le ka hare masapo, sireletsa litaba tse ka hare ka hare ho tloha tshenyo phetha molao feela. A dintho proteinaceous joale ka mathe 'me libakeng tse ling, ho thibela ho bohato ba mahlahana a lik'hemik'hale' mele. Ka mantsoe a mang, mosebetsi sireletsang protheine ke ho fana ka maemo bo hlokehang bakeng sa dithulaganyo tsohle tsa bohlokoa.
