Enzayim phula fat emzimbeni womntu

Le khemikhali yotshintsho ngesondlo abantu indima enkulu okuvunyelwana edlalwe yi amadlala yokwetyisa. Oko kukuthi, secretion zabo. Le nkqubo ngokubambisana ngokungqongqo. Kwisiqwenga zesisu ukutya bayaboniswa bachazelwe kangangoko kwamadlala ezahlukeneyo yokwetyisa. Ngenxa ukungena emathunjini amancinci i-enzayim pancreatic lwenzeka nokwenziwa echanekileyo izakhi kunye nenkqubo eqhelekileyo yokwetyisa. Kuyo eli cebo, indima ebalulekileyo eyadlalwa enzayim kwakufuneka ukuba ndidilize ngamanqatha.

Reaction kunye nokuthotywa

enzyme ke ziwuphose swi umsebenzi kwezinto ukuqhekeka entsonkothileyo efunyenwe kwi phecana zesisu kunye nokutya. Ezi izinto ziba elula, kulula ukufunda loo mzimba. Xa indlela enqanda zokwenza ukutya zidlala indima ekhethekileyo, okanye enzayim ndoyidiliza amafutha (kukho iintlobo ezintathu). Bona eveliswe kwamadlala amathe kunye nesisu, apho enzayim anamathele isixa enkulu kangangoko zenkqunto ephilayo. Ezi zinto ke amafutha, iiprotheni, carbohydrate. Ngenxa yezi enzayim umzimba metabolizes ngokomgangatho Efunyenweyo ukutya. Enzyme ziyafuneka ukuze ukukhawulezisa indlela. uhlobo ngalunye enzyme efanelekileyo yokusabela ethile, ngokwenza uhlobo lonxibelelwano efanelekileyo.

nokwenziwa

Kuba nokwenziwa ngcono kwamafutha emzimbeni isebenza incindi kakhulu esiswini equlethe lipase. Le enzyme lusicande amanqatha, lo injeke uvelisa. Carbohydrate ezidiliziweyo ngenxa amylase. Emva kokuba ukuwa, ukuba bafakwe ngokukhawuleza kwaye ngenisa egazini. Livuleka kwakhona negalelo amathe amylase, maltase, yelactose. Iiproteni ezidiliziweyo ngenxa proteases, ezo nangoku inxaxheba kuqheleke ukuba microflora kweli phecana zesisu. Ezi ziquka pepsin, chymosin, trypsin, carboxypeptidase erepsin nepancreas.

Yintoni na umnxeba enzyme ephambili ukuba uyazifohloza amanqatha emzimbeni womntu?

Lipase - enzyme, umsebenzi wayo ophambili kukuba ukunyibilikisa, fractionation kunye ukwetyisa kwamafutha wokugaya yabantu. amafutha angene emathunjini abakwazi ukuba bangene igazi. Sokufunxa kufuneka kwahlulwa ibe okunamafutha acid kunye glycerol. Kule nkqubo, kwaye kuyanceda lipase. Ukuba kukho Kwimeko apho i-enzayimi uyazifohloza amafutha (lipase) uvikivwa, kuyimfuneko ukuhlola loo mntu ukuba Oncology ngenyameko.

lipase pancreatic njengento proenzyme prolipazy opholileyo akhutshelwa duodenum. Prolipaza isebenze phantsi kwempembelelo asidi duct kolipazy, omnye enzyme yejusi pancreatic. Zeelwimi lipase eveliswa kwiintsana ngenxa amadlala ngomlomo. Yena ebandakanyekileyo xa ukwetyisa ubisi lwebele.

lipase Hepatic secreted kungena egazini, apho enebana nemithambo iindonga zesibindi. Uninzi amanqatha ukutya yaphulwe ezantsi emathunjini amancinci ngenxa lipase pancreatic.

Ukwazi leyo enzyme lusicande amafutha kunye noko akukho ngokukodwa ukubamba umzimba, oogqirha unakho ukumisela zonyango eziyimfuneko.

Le khemikhali uhlobo phantse zonke enzyme - le protini. Le pancreas iyingxenye zombini wokugaya kunye neenkqubo yonyango. Nepancreas ngokwayo ibandakanyeka kwinkqubo ukwetyisa, kwaye enzyme ephambili esiswini na pepsin.

Njengoko enqanda pancreatic ninamathele loo manqatha phezu kwazo izinto ezilula?

Le amylase lusicande le oligosaccharide ukuya istatshi. Ngaphezu koko, oligosaccharides ndoyidiliza waya glucose yintshukumo kwezinye enzyme. Iswekile ifunxwe egazini. Kaloku umzimba womntu ke umthombo wamandla.

Onke amalungu oluntu kunye namalaphu zakhiwa evela njengeprotini. Akukho ngaphandle kunye injeke, leyo isebenze enzayim kuphela emva kokuba ukuqaliswa yabo mithambo ye emathunjini amancinci. Xa ukunyhashwa eqhelekileyo yokusebenza umzimba, pancreatitis kwenzeka. Yinto isifo entle eqhelekileyo. Isifo apho kungekho okunamafutha enzyme lwahlukane, ebizwa insufficiency pancreatic: exocrine okanye yonyango.

iingxaki ukusilela

insufficiency Exocrine kunciphisa imveliso enzyme. Kulo mzekelo, umntu akakwazi ukusebenzisa ukutya njengomsebenzi of triglycerides lwahlukane badlabhuka ininzi kakhulu. Kwezi izigulane, iimpawu isicaphucaphu lwenzeka emva kokungenisa ukutya okunamafutha, ubukhali iintlungu esiswini.

Xa ezidalwe okubangelwa akakwazi ukuvelisa i-insulin hormone, nto leyo inceda lokugaya iswekile. Kukho sisifo kakhulu ekuthiwa seswekile. Elinye igama - na isifo seswekile iswekile. Eli gama lu dityanisiwe ukwanda netuwa umzimba umchamo, apho ithe amanzi kunye umntu uziva omile rhoqo. Carbohydrate phantse musani zivela egazini kungena iiseli kwaye, ngenxa yoko, musa zisetyenziselwa iimfuno zamandla komzimba. Isalathisi glucose igazi kwandisa kakhulu, kwaye iqala ukuba imveliso ngokusebenzisa yokuchama. Ngenxa ezi nkqubo ukusetyenziswa kwamafutha kunye leeprothini iinjongo amandla, yande kakhulu, yaye umzimba oluhlala iimveliso igcwala buso. Ekugqibeleni, kakhulu, oko konyusa ubumuncu egazini, leyo enokude ikhokelele isiqaqa seswekile. Kulo mzekelo, isigulane ukuphefumla disorder, wada wafa isiqaqa nokufa.

Lo mzekelo kuyabonakala kakuhle ukuba ndidilize indlela enzayim ebalulekileyo kwamafutha emzimbeni kwabantu, ukuze onke amalungu zisebenza ngokuvisisanayo.

glucagon

Ukuba kukho naziphi na iingxaki, qiniseka ukuba ukujongana kubo, ukunceda umzimba ngokusebenzisa iindlela ngeendlela zonyango kunye namayeza.

Glucagon na isiphumo esahlukileyo amanyathelo insulin. Le isiphumo ihomoni phezu kukwahlukana glycogen esibindini kwaye ukuguqulwa carbohydrate ezityebileyo, loo nto iyakubangela ukunyuswa xi glucose egazini. A somatostatin hormone uthwala inhibition of glucagon secretion.

self-unyango

Xa amayeza, enzyme ukuba kwamafutha ninamathele emzimbeni womntu, ungakwazi ukufumana nge amayeza. A lot of them - ukusuka iintlobo ezininzi edumileyo kancinane waziwa ngaphantsi ayabiza, kodwa esebenzayo efanayo. Into esemqoka - ukuba self-medicate. Ngapha koko, kuphela ugqirha usebenzisa ubuchule obufanelekileyo diagnostic, sinokufumana imveliso ekunene ukuba kuqheleke iphecana zesisu.

Noko ke, sinceda kuphela umzimba enzyme. Kunzima ukuyenza isebenze ngokuchanekileyo. Ingakumbi xa umntu sele emdala. Kuyinto kuphela efika kuqala kubonakala ukuba uthenge iipilisi eziyimfuneko - kwaye ngxaki isonjululwe. Enyanisweni, ukuba akukho njalo. Umzimba womntu - yindlela ephelele, kunjalo nje ukwaluphala kwaye banxibe. Ukuba umntu ufuna yayisebenza kuye elide kangangoko kunokwenzeka, kuyimfuneko ukugcina oko ngexesha lokuba ukuxilonga nokunyanga.

Kakade ke, ukufunda nokufundisa, okuthi enzyme uyazifohloza kwamafutha kwinkqubo zokwetyisa komntu, ungaya ekhemesti ucele ayinikiwe ukuncoma ichiza lulwakhiwo oyifunayo. Kodwa oku kunokwenziwa kuphela kwiimeko ezizodwa apho, ngenxa ezinye izizathu olungileyo ukutyelela ugqirha okanye mema ukuba indlu. Kufuneka iqondwe ukuba singakwazi iphutha kunye iimpawu zizifo ezahlukahlukeneyo kunokuba efanayo. Kwaye ukuze wenze ukuxilongwa echanekileyo, qiniseka ukuba udinga uncedo lonyango. Self-iyeza angafaka kakubi.

Ekugayeni esiswini

juice esiswini iqulethe pepsin, zehydrochloric acid kunye lipase. Pepsin enza kuphela i medium acid kunye lusicande neeproteni zibe peptides. Lipase e lusicande incindi esiswini emulsified kuphela ezityebileyo (milk). Yaphula fat enzyme lusebenza kuphela kwimeko-alkali ze emathunjini amancinci. Yena uya kunye nokwakhiwa ukutya semi-oluludaka, ukusika betekisi izihlunu kakuhle isisu. It zityhalelwa kulo duodenum ngokwamaqela. Abanye isabelo esincinane wendele izinto ezininzi esiswini (iswekile, ityuwa zichithakala nje, utywala, namayeza afanelekileyo). kanye Inkqubo ukwetyisa ngokubanzi iphela emathunjini amancinci.

Kuba kulo ukutya duodenum phambili engena enyongweni, amathumbu kunye ayo pancreatic. Ufumana ukutya esiswini, waya kwezona ziseza ntsi ngezantya ezahlukeneyo. Amafutha ilibele, kwaye ubisi idlule ngokukhawuleza.

lipase

juice pancreatic - a ialakalin engamanzi, ayinazo umbala kunye trypsin equlethe kunye nezinye enzayim anamathele peptides zibe acid. Amylase, yelactose kunye maltase ukuguqula namandla zibe glucose, fructose kunye lactose. Lipase - enzayimi uyazifohloza nezikhongozelo zibe okunamafutha acid kunye glycerol. Le yokwetyiswa juice zinomgutyulo zixhomekeke uhlobo kunye nomgangatho ukutya.

emathunjini amancinci kunye isinyi yenza ukugaywa Parietal. Emva unyango ngoomatshini kunye enzymatic yeemveliso cleavage iye yangena egazini kunye nkovu. Le yinkqubo entsonkothileyo komzimba ukuba yenzelwa villi ubhityile ikhadi emathunjini kunye ngokungqongqo wayalela kwicala elinye ukusuka villi ethunjini.

sokufunxa

asidi acid, iivithamini, iswekile, iityuwa izimbiwa kwi isisombululo nokwakheka zolwelo bafakwe villi igazi capillary. Glycerol uyadinga acid ayichithwanga yaye wendele imicu abakwazi. Baya kucanda kulo iiseli epithelial, nto leyo yenze iimolekyuli ezityebileyo engena nkovu. Bephumelele ukungakwazi kwiindawo nkovu, ukuba zikhutshelwa egazini.

kubaluleke kakhulu xa amanqatha otyiwa udlala inyongo. okunamafutha acid kunye inyongo nokuxhuma ngealkali, saponified. Ngaloo kwakhiwa isepha (iityuwa ezinyibilikayo of okunamafutha acid), ngokulula acandacanda eludongeni villi. Amadlala kwi Amathumbu amakhulu ubukhulu becala cell yencindi yomlomo. Amathumbu amakhulu afunxa amanzi ukuya iilitha-4 ngosuku. Ulikhaya inani elikhulu kakhulu iintsholongwane ababandakanyekayo yokuwa neselulosi kunye Yindibanisela iivithamini B no-C
