Pepsin - te pūmua whākōkī e piri pūmua i roto i te taiao waikawa. Kei te whakaputaina te reira e kaiao o whāngote me ngā ngārara, ngā māngai o te piha haapiiraa o manu, me te maha ika.

no whākōkī Vauvauhia ki te pūmua o te momo flare, kua he taimaha o e pā ana ki 34500. muingota māngai iho rite te mekameka polypeptide ngā o toru rau e wha tekau waikawa amino rāpoi. I roto i tona hanganga kei hoki HPO3 me toru pūāhua hononga disulfide.

Kei te whānui Pepsin whakamahia i roto i te take hauora, me te cheesemaking. I roto i te taiwhanga e whakamahia ana e ia mo te ako atu taipitopito o te pūhui pūmua, ara, te hanganga pūmua tuatahi. Pepsin Ko te inhibitor tūturu - pepstatin.

He momo o te pūmua whākōkī

He ma rua isoforms Pepsin. Rerekētanga i waenganui i poinanaha katoa e rite pepsin āheinga nekeneke electrophoretic inaktivatsionnyh tikanga, te mahi proteolytic. pepsin Kaitāutu - CF 3. 4. 23. 1.

Ko te tangata i roto i te wai puku e whitu momo o pepsin kei, ka e koi wehewehea e rima o ratou i roto i te maha aravihi:

1. Mau pepsin (A) E te mahi mōrahi i roto i te reo pH 1.9, me ki he hua ki runga, ki te 6 inactivated.
2. Pepsin 2 (B) he kaha rite taea i roto i te reo o te pH = 2.1.
3. Momo 3 whakaaturia te te tohu teitei o te mahi i te pH = 2.4-2.8.
4. Momo 5, hoki e mohiotia ana gastriksin kua te tohu teitei o te mahi i te pH = 2.8-3.4.
5. Momo 7 i pH = 3.3-3.9 tohu e te mahi rawa.

Te tikanga whākōkī nakunaku

tukua Pepsin te i roto i te repe pekitīlia o te puka taupāhohea (pepsinogen), engari te mahi ano whākōkī whakahohetia te waikawa pūmāota. I raro i tona mana, haere reira ki te puka taea. He tikanga matua mō te mahi o te pepsin whākōkī ko te aroaro o te taiao waikawa, i te mea he aha te whakawhitinga o pepsin i roto i te duodenum ngaro reira tona mahi, pera i roto i te taiao kawakore piro. Pepsin whākōkī noho he wāhi matua i roto i te nakunaku o te piha haapiiraa katoa o kararehe, a rawa te tangata. Tenei taonga decomposes pūmua kai ki iti mekameka peptide me waikawa amino.

hua tangata me nga wahine i tenei whākōkī rerekē tohu. I roto i te tangata, hoki a tawhio noa e rua tekau ki te toru tekau karamu o pepsin ia haora, ia te wahine - e rua tekau ki te toru tekau ōrau iti. Nga pūtau tuatahi, whakatupuranga o wāhi pepsin, kua taratahi reira i roto i te puka o te pepsinogen pakaru. I muri wāhinga o nga peptides ki te nui etahi o N-mutunga pepsinogen haere ki te puka hohe. Te whakakōkī i roto i te tauhohe o te tauhohe matū mahi waikawa pūmāota. Pepsin peptidase me protease roaa āhuatanga me te kawenga mō te pūmua disaggregation.

pakihi Medical

I roto i te rongoa pepsin Kei te whānui whakamahia reira rite te medicament i roto i etahi mate e pā ana ki te kore o te hanga o tenei pūmua whākōkī i roto i te puku o te manawanui. Tango rennet whākōkī pepsin i puku porcine kiriuhi mucous. Ko wātea i roto i te puka o papa te tarukino, opupu decomposed e te hawhekaihe acidin puehu ranei. Pepsin Ko te mema o me etahi taero ngā. Kua ATC waehere A09AA03. Tauira o te māuiuitanga i roto i nei pepsinosoderzhaschie rongoā tikanga he mate o Menetrier.

pepsin Beef - he ...

Rennet mīti whākōkī pepsin - tetahi o te pai-mohiotia me tino pinepine whakamahia ngā puka o tenei taonga. Ano he paru whakaputaina i roto i te wha o nga puku o te kuao kau. Te raau e whakamahia ana i roto i te hanga, kua hanga e e rua whākōkī: pepsin me chymosin moni fakanatula hautanga. Rennet whakamahia i roto i te tīhi production, me tona mahi matua - te waiu, katinga hanganga me te whai wāhi i roto i te tukanga o te matuatanga o ngā hua tīhi me te tiihi.

tukua te Beef pepsin i te puku o nga kararehe, me te hanga o ngā hua mō te hoko, haere reira i roto i rua ngā wāhanga o te purenga o te pūmua whākōkī i te ngako me te poke e he rewakore. Ko te tukanga o te hanga Bovine pepsin haere e rave rahi ngā wāhanga: tukanga tangohanga, te waitote-i roto i, me te whāhau whakamaroke.

Ētahi atu tono

Kei te tāpiri te pepsin paru ki te rīriri. Kei te whakamahia hoki te reira i roto i te tīhi production. pepsin rennet takirua ki chymosin hanga te taua paru whakamahia ki hinga te waiu.

Whakakopa tukanga waiu pūmua coagulation karanga reira, ara casein ki te hanga i te rā i runga i te waiu, pūtake. Casein he āhua motuhake te hanganga, me kotahi anake here peptide he kawenga mō te momo enzymatic o pūmua upoo-. Matatini ki pepsin me chymosin ano he kawenga mo te whati o te hononga iho ka arata'i ki coagulation o te waiu.

mutunga

Whakarāpopoto, ka taea e tatou te mea e tenei whakauru kaha ko tetahi o te whākōkī tino nui wāhi i roto i te nakunaku o kai i roto i te kopu o nga māngai o maha akomanga o mea ora. I roto i te hanga o te rongoā me te taonga kei te nuinga whakamahia rite te rongoā, me te tapiritia ki rennet mo te hanga o ngā hua waiu, me te tiihi.
