Enzymes uas zom cov roj nyob rau hauv tib neeg lub cev

Nyob rau hauv lub tshuaj hloov dua siab tshiab txais yuav tib neeg kev noj haus luag hauj lwm loj ua si los ntawm lub digestive qog. Namely, lawv secretion. Qhov no tus txheej txheem no nruj me ntsis hauj lwm ua ke. Nyob rau hauv lub mob huam cov zaub mov yog raug mus rau ntau yam digestive qog. Vim mus nkag rau hauv cov hnyuv lub pancreatic enzymes tshwm sim muaj tseeb assimilation ntawm cov as-ham thiab ib txwm digestive txheej txheem. Thoob plaws hauv no tswvyim, qhov tseem ceeb luag hauj lwm ua si los ntawm cov enzymes uas yuav tsum tau mus ua txhaum down rog.

Cov tshuaj tiv thaiv thiab degradation

Digestive enzymes yog narrowly teem ua hauj lwm ntawm splitting complex tshuaj tau txais nyob rau hauv lub mob huam rau cov zaub mov. Cov tshuaj yog tawg cia rau hauv tej yam yooj yim, yooj yim mus kawm tau hais tias lub cev. Nyob rau hauv lub mechanism ntawm cov zaub mov ua enzymes ua si ib tug tshwj xeeb lub luag hauj lwm, los yog cov enzymes uas zom cov roj (nws muaj peb hom). Lawv yog ua los ntawm cov qaub ncaug thiab lub plab, qhov twg enzymes muab siab npuab ib tug ncaj loj npaum li cas ntawm cov organic teeb meem. Cov tshuaj yog cov rog, cov nqaijrog, carbohydrates. Raws li ib tug tshwm sim ntawm cov enzymes lub cev metabolizes qualitatively txais khoom noj khoom haus. Enzymes uas yuav tsum tau mus leeb cov tshuaj tiv thaiv. Txhua yam ntawm enzyme yog haum rau ib tug kev tshuaj tiv thaiv, los ntawm ua yeeb yam nyob rau hauv lub tsim nyog kev twb kev txuas hom.

assimilation

Rau zoo dua assimilation ntawm cov rog hauv lub cev ua haujlwm pais plab kua txiv uas muaj lipase. Qhov no enzyme cleaves roj, lub pancreas ua. Carbohydrates raug tawg cia vim lub amylase. Tom qab lub cev qhuav dej, lawv sai sai absorbed thiab nkag mus rau hauv cov hlab ntsha. Splitting kuj pab txhawb rau muaj qaub amylase, maltase, lactase. Cov nqaijrog raug tawg cia vim lub proteases, uas yog tseem muab kev koom tes nyob rau hauv lub normalization ntawm lub microflora ntawm tus mob huam. Cov no muaj xws pepsin, chymosin, trypsin, carboxypeptidase erepsin thiab txiav.

Yuav ua li cas koj hu mus rau lub ntsiab enzyme uas lov rog nyob rau hauv tib neeg lub cev?

Lipase - ib qho enzyme, uas nws lub ntsiab hauj lwm yog los yaj, fractionation thiab kev zom ntawm cov rog hauv cov tib neeg digestive ib ntsuj av. rog los mus rau hauv cov hnyuv yog tsis muaj peev xwm yuav absorbed rau hauv cov ntshav. Suction yuav tsum muab phua rau hauv fatty acids thiab glycerol. Nyob rau hauv tus txheej txheem no, thiab nws yuav pab lipase. Yog hais tias muaj yog ib rooj plaub uas ib qho enzyme uas lov roj (lipase) yog nws txo qis, nws yog tsim nyog los xyuas tus neeg Oncology kom zoo zoo.

Pancreatic lipase li ib tug tsaug zog proenzyme prolipazy yog tawm mus rau hauv lub duodenum. Prolipaza tshuab txais nyob rau hauv tus ntawm cov kua tsib acids thiab kolipazy, lwm enzyme ntawm pancreatic kua txiv. Lingual lipase ua nyob rau hauv cov me nyuam mos vim lub qhov ncauj qog. Nws yog kev koom tes nyob rau hauv lub plab zom mov ntawm lub mis mis nyuj.

Hepatic lipase secreted mus rau hauv cov hlab ntsha, qhov twg nws uake rau vascular phab ntsa siab. Feem ntau ntawm cov roj los ntawm khoom noj khoom haus yog lawm cia nyob rau hauv cov hnyuv vim pancreatic lipase.

Paub uas enzyme cleaves rog thiab dab tsi yog tsis tau lis lub cev, cov kws kho mob yuav muab tshuaj rau qhov tsim nyog kho mob.

Cov tshuaj xwm ntawm yuav luag tag nrho cov enzymes - qhov no protein. Cov txiav yog ib qho khoom hauv nrog cev ntawm ob lub digestive thiab endocrine systems. Txiav nws tus kheej yog kev koom tes nyob rau hauv tus txheej txheem ntawm kev zom, thiab lub ntsiab pais plab enzyme yog pepsin.

Raws li pancreatic enzymes muab siab npuab cov roj rau tej yam yooj yim cov khoom?

Lub amylase cleaves lub oligosaccharide mus rau lub hmoov txhuv nplej. Ntxiv mus, oligosaccharides zom rau hauv zib los ntawm cov kev txiav txim ntawm lwm yam digestive enzymes. Qabzib yog absorbed rau hauv cov hlab ntsha. Rau cov tib neeg lub cev nws yog ib qhov chaw ntawm lub zog.

Tag nrho cov tib neeg nruab nrog cev thiab cov nqaij yog ua los ntawm proteins. Tsis kos thiab tus txiav, uas activates enzymes tsuas yog tom qab lawv cov kev taw qhia mus rau hauv lub lumen ntawm cov hnyuv. Thaum ua txhaum ntawm lub cev tau hauj lwm ntawm lub cev, pancreatitis tshwm sim. Nws yog ib tug zoo nkauj heev tus kab mob. Kab Mob nyob rau hauv uas tsis muaj enzyme splitting rog, hu ua pancreatic insufficiency: exocrine los yog endocrine.

tsis ua hauj lwm teeb meem

Exocrine insufficiency thiaj zus tau tej cov digestive enzymes. Nyob rau hauv cov ntaub ntawv no, ib tug neeg muaj peev xwm siv tsis tau khoom noj khoom haus raws li ib tug muaj nuj nqi ntawm splitting triglycerides tawg nyob rau hauv loj tagnrho.

Thaum endocrine tsis muaj peev xwm tsis muaj peev xwm tsim tau cov tshuaj insulin, uas yuav pab metabolize qab zib. Muaj yog ib tug loj heev kab mob hu ua ntshav qab zib. Lwm lub npe - yog qab zib cov ntshav qab zib. Qhov no lub npe yog txuam nrog ib qho kev nce rau hauv lub cev tsis muaj kua ntawm cov zis, uas nws loses dej thiab tus neeg pom tau tias ib qhov nqhis dej. Carbohydrates yuav luag tsis tuaj los ntawm cov ntshav mus rau hauv lub hlwb thiab, yog li ntawd, tsis yog siv rau lub zog kev xav tau ntawm lub cev. Qhov taw qhia ntawm cov ntshav piam thaj tsub kom sharply, thiab nws pib mus yuav tso zis los ntawm cov zis. Vim cov dab siv roj thiab protein rau lub zog lub hom phiaj yog zoo heev ntau zog, thiab lub cev accumulates ib nrab oxidation khoom. Thaum kawg, dhau lawm, nws yuav tsub kom lub acidity nyob rau hauv cov ntshav, uas muaj peev xwm txawm ua rau ntshav qab zib coma. Nyob rau hauv cov ntaub ntawv no, tus neeg mob yog ua tsis taus pa tsis meej, kom txog thaum nws poob nco qab thiab tuag.

Qhov kev piv txwv muaj peev xwm yuav pom zoo heev yuav ua li cas ib qho tseem ceeb enzymes uas zom cov roj nyob rau hauv lub cev ntawm cov neeg, rau tag nrho cov kabmob ua hauj lwm sib haum xeeb.

glucagon

Yog hais tias muaj tej yam teeb meem, yuav tsum mus rau qhov lawv, pab tau lub cev los ntawm ib tug ntau yam ntawm txoj kev kho mob thiab cov tshuaj noj.

Glucagon muaj cov lus rov nyhuv ntawm insulin kev txiav txim. Qhov no lawm ntxim rau cov splitting ntawm glycogen nyob rau hauv lub siab thiab nyob rau hauv lub hloov dua siab tshiab ntawm roj carbohydrates, li no ua rau kev nce ntawm cov concentration ntawm qab zib nyob rau hauv cov ntshav. Ib tug lawm somatostatin yog inhibition ntawm glucagon secretion.

self-kev kho mob

Nyob rau hauv cov tshuaj, cov enzymes uas muab siab npuab rog nyob rau hauv tib neeg lub cev, yuav tau txais ntawm cov tshuaj. Ib tug ntau ntawm lawv - los ntawm lub npe nrov tshaj hom rau cov me-paub thiab tsis tshua kim, tab sis tib zoo. Qhov loj tshaj plaws - tsis rau nws tus kheej-medicate. Tom qab tag nrho, tsuas yog ib tug kws kho mob siv kom tsim nyog diagnostic hom kev kawm, muaj peev xwm nrhiav tau txoj cai khoom rau lub normalization ntawm tus mob huam.

Feem ntau, txawm li cas los, peb tsuas pab tau lub cev nrog enzymes. Yam yuav ua rau nws ua hauj lwm zoo. Tshwj xeeb tshaj yog yog ib tug neeg twb laus laus lawm.

Thiab nyob rau hauv thiaj li yuav ua tau ib tug tseeb mob, nco ntsoov xav tau kev pab kho mob. Self-tshuaj muaj tiag ua mob.

Plab zom mov nyob rau hauv lub plab

Pais plab kua txiv muaj pepsin, hydrochloric acid thiab lipase. Pepsin ua xwb nyob rau hauv ib tug acid nruab nrab thiab cleaves cov nqaijrog rau hauv peptides. Lipase nyob rau hauv pais plab kua txiv cleaves tsuas emulsified roj (mis nyuj). Zom roj enzyme yuav dhia xwb nyob rau hauv lub alkaline ib puag ncig ntawm cov hnyuv. Nws mus nrog nyob tus yeees ntawm cov khoom noj khoom haus semi-slurry, tej lub ntiab tus nqaij ntawm lub plab. Nws yog thawb mus rau hauv lub duodenum nyob rau hauv cooling. Ib txhia me me feem absorbed ntau yam nyob rau hauv lub plab (qab zib, yaj ntsev, haus dej cawv, pharmaceuticals). Tus heev txheej txheem ntawm kev zom feem ntau xaus nyob rau hauv cov hnyuv.

Rau advanced mus rau hauv lub duodenum zaub mov nkag mus rau hauv cov kua tsib, plab hnyuv thiab pancreatic juices. Tau txais zaub mov los ntawm lub plab rau hauv lub qis qhov chaw nyob rau txawv speeds. Rog yog ncua, thiab cov mis nyuj kis sai sai.

lipase

Pancreatic kua txiv - ib tug ua kua alkaline, uas muaj tsis muaj xim thiab muaj trypsin thiab lwm yam enzymes uas muab siab npuab peptides rau hauv amino acids. Amylase, lactase thiab maltase hloov carbohydrates rau hauv qabzib, fructose thiab lactose. Lipase - ib qho enzyme uas lov cov nqaijrog rau hauv fatty acids thiab glycerol. Cov kev zom thiab feem kua txiv nyob ntawm seb lub hom thiab tsis zoo ntawm cov khoom noj.

Hnyuv thiab lub zais zis ua parietal digestion. Tom qab txhua yam thiab enzymatic kev kho mob ntawm lub cleavage khoom yog absorbed rau hauv cov ntshav thiab cov qog. Qhov no yog ib txoj sia uas yog ua villi nyias card hnyuv thiab nruj me ntsis qhia nyob rau hauv ib tug kev taw qhia los ntawm cov plab villi.

suction

Amino acids, vitamins, qabzib, mineral ntsev nyob rau hauv lub aqueous tov muaj pes tsawg leeg absorbed rau hauv capillary ntshav villi. Glycerol thiab fatty acid yog tsis yaj thiab absorbed fibers tsis tau. Lawv dhau mus rau hauv lub epithelial hlwb, uas tsim muaj roj molecules nkag mus rau hauv lub qog. Thaum dhau lub teeb meem ntawm lub qog, lawv tso rau hauv cov hlab ntsha.

Heev tseem ceeb thaum rog kom tsawg plays bile. Fatty acids thiab cov kua tsib txuas nrog alkali, saponified. Yog li tsim tshuaj ntxuav tes (soluble ntsev ntawm fatty acids), yooj yim dua los ntawm cov phab ntsa hauv cov villi. Lub qog nyob rau hauv txoj hnyuv loj feem ntau paim hnoos qeev. Hnyuv loj absorbs dej mus txog rau 4 liv ib hnub twg. Nws yog lub tsev mus rau ib tug heev loj tus naj npawb ntawm cov kab mob muab kev koom tes nyob rau hauv lub neej puas cellulose thiab lub synthesis ntawm cov vitamins B thiab C.
