Yonke into ngalo pepsin enzyme

Eli nqaku lujolise enzyme edlalwa ezisegumbini isisu zonke esanyisayo, kuquka abantu. ngamagqabantshintshi pepsin enzyme, ulwazi malunga isomers yayo, kuya kuxoxwa kunye nendima arhente kwiinkqubo ukwetyisa.

izimvo ngokubanzi

Okokuqala, makhe sibone ukuba yintoni udidi enqanda ziquka pepsin. Oku kuza kuvumela ulwazi olunzulu isihloko ngokwayo.

Le proteolytic enzyme pepsin inxulumene udidi hydrolases obuvelisiweyo kunye isifo esiswini, yaye umsebenzi yayo ephambili ukuqhekeka iiprothini makaye ukutya, ukuze peptides. Pepsin - enzyme lusicande iiproteni kwi imeko asidi. Oku eziveliswa zizinto yezilwanyana kunye ezirhubuluzayo, abameli iklasi iintaka kunye neentlanzi ezininzi.

enzyme thaca fanele kwiiproteni yohlobo globular, uzelwe enobunzima beemolekyuli malunga 34500. molecule ngokwalo zimelwe inxitywe polypeptide iquka yayingamakhulu amathathu mane acid. Kumafa zaso iqulethe HPO3 kunye uxhulumaniso disulfide umlinganiswa ezintathu.

Pepsin lisetyenziswa kwimeko zonyango kunye cheesemaking. Kwiilebhu isetyenziselwa isifundo olubanzi iikhompawundi protein, oko kukuthi, ubume ziiprotein zaseprayimari. Pepsin i inhibitor yendalo - pepstatin.

Iintlobo enzyme

Pepsin uye isoforms elinambini. Umahluko phakathi zonke isomers yile ubuchule motor pepsin electrophoretic inaktivatsionnyh iimeko, umsebenzi proteolytic. Isazisi pepsin - CF 3. 4. 23. 1.

Le ndoda kwincindi esiswini iqulethe iindidi ezisixhenxe pepsin, yaye abahlanu kubo kabukhali lahlulwe ngokwezikhundla ezininzi:

1. Eneneni pepsin (A) lenze umsebenzi eliphezulu kwixesha eliphakathi pH 1.9, kunye nokwanda ukuya ku-6 inactivated.
2. Pepsin 2 (B) iyasebenza kangangoko kunokwenzeka kwi njengolwimi pH = 2.1.
3. Uhlobo 3 iyaboniswa iqondo eliphezulu umsebenzi kwi pH = 2.4-2.8.
4. Type 5, okwabizwa ngokuba gastriksin unalo iqondo eliphezulu umsebenzi kwi pH = 2.8-3.4.
5. Type 7 pH = 3.3-3.9 imiqondiso unawo umsebenzi liphezulu.

Meaning enzyme ekugayeni

Pepsin ngesi amadlala esiswini le fom zingasebenzi (pepsinogen), kodwa umsebenzi ngokwawo enzyme usebenze zehydrochloric acid. Elizaliswe yimpembelelo yayo, iya ibe luhlobo olusebenzisekayo. Eyona nto ifunekayo ukuze umsebenzi lo pepsin enzyme phambi kokusingqongileyo asidi, nto ke leyo ebangele ukuba utshintsho lwe pepsin kwi duodenum ithe umsebenzi wayo, njengoko kwimekobume emathunjini obrak. Pepsin enzyme ithatha indima ephambili ukwetyisa yonke yeklasi ezanyisayo, kwaye ingakumbi abantu. Le into abole iiproteni ukutya imixokelelwane peptide ezincinane kunye acid.

Amadoda nabafazi avelisa le enzayim izikhombisi ziyahluka. Ngabantu, ngokuba grams malunga namashumi amabini ukuya kwamathathu of pepsin ngeyure nganye, lo gama umfazi - amabini ukuya kumashumi amathathu ekhulwini ngaphantsi. Iiseli ephambili, isizukulwana kwendawo pepsin, oko uyazimela ngokohlobo pepsinogen ezaphukileyo. Emva cleavage le peptides kunye isixa esithile-ekupheleni N pepsinogen ingena uhlobo esebenzayo. Lo kuvala indlela abasabela zeekhemikhali usebenza zehydrochloric acid. Pepsin peptidase kunye protease ayiphetheyo iipropati kwaye linoxanduva ziiprotein ahlazululwe.

ishishini Medical

Xa iyeza pepsin lisetyenziswa njengendlela medicament kuzo izifo ezithile ezinxulumene ndiswele kuveliswe le enzyme isisu yesigulane. Caphula rennet enzyme pepsin esiswini kweeHagu ngenwebu yangaphakathi. Ichiza ifumaneka ngohlobo amacwecwe, namadyungudyungu ibolile ngumntu admixture acidin okanye emigutyeni. Pepsin lilungu kunye nezinye iziyobisi ezidibeneyo. Ngaba ATC ikhowudi A09AA03. Imizekelo leengxaki apho pepsinosoderzhaschie amayeza emiselweyo izifo Menetrier kaThixo.

Beef pepsin - a ...

Rennet enzyme pepsin yenkomo - enye iifom kakuhle yaziwa kwaye zisetyenziswe qho weli. Wona enzyme eveliswa esiswini yesine thole. Ichiza ezisetyenziswa zemveliso, ukhandwa enqanda ezimbini: pepsin kunye chymosin izixa umlinganiselo ngokwendalo. Rennet ezisetyenziswa kwimveliso samasi, kwaye umsebenzi wayo ophambili - ubisi ihlwili ukubunjwa inxaxheba kwinkqubo nokwanda samasi kunye netshizi iimveliso.

Beef pepsin ekhululwa nezisu iinkomo kunye nokuveliswa kwemveliso ngenxa yentengiso, udlula izigaba ezimbini ucoco enzyme ukusuka amanqatha ubumdaka ezithi ezingenakunyibilika. Inkqubo yokwenza inkomo pepsin kudlula izigaba ezininzi: inkqubo le gesi, yityuwa-out kunye sublimation yokomisa.

Okunye Izicelo

Le pepsin enzyme lifakiwe ijike. Kwakhona isetyenziswa kwimveliso samasi. pepsin Rennet ngezibini kunye chymosin zenza i-enzayim usetyenziswa ukuba sibutyake ubisi.

Yokusonga inkqubo obisi coagulation kubiza ngayo, eyile casein ukwenza gel rhoqo ubisi. Casein kukho imeko ethile isakhiwo, yaye omnye kuphela bond peptide inoxanduva uhlobo enzymatic protein ekunqandeni. Complex ne pepsin kunye chymosin ngokwayo unoxanduva ikhefu yokuqhagamshelwa ngokwawo kwaye ikhokelela coagulation yobisi.

isiphelo

Ukushwankathela, sinokuthi le esisebenza ngomnye enzayim ibalulekileyo ababandakanyekayo ukwetyisa ukutya kwelo isisu abameli kwiiklasi ezininzi eziphilayo. Ekuvelisweni kweti i-amayeza kunye ubuncwane kakhulu isetyenziswa amayeza, kwaye yongezwe rennet ukuba imveliso yobisi kunye netshizi iimveliso.
