Pepsinogen yog lub plab zom mov zais cia los ntawm lub plab phab ntsa ntawm tib neeg thiab ntau hom tsiaj. Raws li kev cuam tshuam ntawm acidic ib puag ncig ntawm lub plab (pH nyob ib ncig ntawm 2) lossis pepsin nws tus kheej (hu ua autoactivation), nws hloov mus rau pepsin, uas nws lub luag haujlwm tseem ceeb yog ua ntej zom cov protein. Thaum lub sij hawm kev zom zaub mov, pepsin lov cov proteins rau hauv luv luv chains ntawm polypeptides thiab oligopeptides, uas tom qab nyob rau hauv lub digestive txheej txheem noj qhov chaw nyob rau hauv cov hnyuv me yog tawg mus rau hauv ib tug neeg amino acids. Raws li kev cuam tshuam ntawm cov stimuli ntxiv, xws li cov zaub mov hauv lub plab lossis acidification ntawm mucosa, nws cov secretion nce.
Pepsin - siv tshuaj kho mob
Cov tshuaj yog tau los ntawm lub plab mucosa ntawm npua, nyuj los yog yaj. Protein digestion pib ntawm pH tsawg dua 4; siab heev ntawm hydrochloric acid inactivate Pepsi. Kev npaj pepsyny Lawv ua kom qab los noj mov, normalize pH ntawm cov kua txiv hmab txiv ntoo, thiab pab txhawb kev zom cov protein.
Pepsin - cov lus qhia
Kev npaj muaj Pepsi thov:
- nyob rau hauv cov kab mob uas tsis txaus endogenous pepsin secretion,
- thaum tsis qab los noj mov,
- nyob rau hauv acid,
- nyob rau hauv txo gastric secretion,
- nyob rau hauv mob gastritis,
- cov txheej txheem fermentation ntau dhau,
- nyob rau hauv mob thiab mob ntev gastritis,
- cov xwm txheej tom qab gastrectomy,
- digestive mob tshwm sim los ntawm kab mob siab.
Cov tsos mob ntawm acidosis thiab acidity tej zaum yuav zoo sib xws, yog li kev kuaj mob tseem ceeb. Cov neeg mob feem ntau yws yws txog cov tsos mob tsis zoo sai tom qab noj mov. Cov no yog: ib qho kev xav ntawm overflow, mob nyob rau hauv lub plab thiab nws ib puag ncig, kev xav ntawm hnyav nyob rau hauv lub plab cheeb tsam. Tej zaum yuav muaj roj, kub hnyiab, flatulence, xeev siab, los yog muaj teeb meem nrog lub plab zom mov xws li raws plab lossis cem quav. Qee zaum raws plab thiab cem quav. Ntev ntev raws plab yog qhov ua rau lub cev tsis muaj zog thiab ua rau tus neeg mob tsis muaj zog. Mob tsis zom zaub mov kom raug, tsis nqus cov micro- thiab macroelements tsim nyog. Thaum lub plab tsim kua txiv digestive tsawg dhau, cov zaub mov tsis tuaj yeem zom tau zoo. Cov khoom xyaw uas nyuaj rau zom los yog ua tsis tau zoo (ua tsis tiav, zom tsis tiav) tsuas yog ua tiav ib nrab, tsim nyog rau lawv kom siv tag nrho thiab assimilated. Nov yog vim li cas tsis txausHlau yog qhov nyuaj tshaj plaws los muab thaum koj muaj kua qaub, vim nws feem ntau pom hauv cov nqaij, uas nyuaj rau zom. Kuj tseem muaj malabsorption ntawm magnesium, zinc (li no, inter alia, teeb meem ntawm daim tawv nqaij, rau tes thiab plaub hau) thiab calcium. Kev tshawb fawb pom tau tias qhov tseeb ntawm hydrochloric acid yog qhov tsim nyog rau kev nqus cov vitamins B, tshwj xeeb tshaj yog cov vitamin B12. Qhov tsis txaus ntawm cov vitamin no cuam tshuam nrog kev mob ntshav qab zib, kev tsis muaj zog lossis kev ua haujlwm ntawm lub paj hlwb, piv txwv li kev nyuaj siab. Peb kuj tseem yuav muaj kev tiv thaiv tsis zoo rau kev kis kab mob, vim tias kev nqus ntawm vitamin C yog qhov phem dua rau cov neeg uas tsis muaj plab acid. Yog tias muaj cov tsos mob zoo sib xws, mus ntsib kws kho mob. Qhov zoo sib xws ntawm cov tsos mob ntawm gastric hyperacidity thiab acidity yuav tsum tau kuaj xyuas kom zoo, thiab los ntawm kev ncav cuag cov tshuaj antacids nrov, peb tuaj yeem ua mob rau peb tus kheej.
Pepsin - ntau npaum li cas
Qhov ntau npaum li cas yog txiav txim ib tus zuj zus nyob ntawm qhov kev npaj, qhia rau nws siv thiab tus neeg mob tus mob. Kev npaj pepsyny muab tshuaj tam sim ua ntej lossis thaum noj mov.
Kev npaj ntawm lub khw Polish muaj Pepsimuaj nyob rau hauv cov khw muag tshuaj yog:
- Citropepsin (kua),
- Bepepsin (cov ntsiav tshuaj),
- Mixtura Pepsini, pepsin sib tov (kua) - muaj nyob rau hauv daim ntawv tshuaj ntawm lub tsev muag tshuaj.
Pepsina nws kuj yog ib feem ntau ntawm cov khoom noj khoom haus los pab txhawb kev zom zaub mov lossis sib ntaus rog rog.
