Cov kua tsib pab hauv kev zom zaub mov ntawm lipid, feem ntau yog triglycerides, dhau los emulsification . Emulsification yog ib qho txheej txheem uas loj lipid globules tau tawg mus rau hauv ob peb lub lipid globules. Cov bile ua ntsev nyob ib puag ncig cov saw ntev fatty acids thiab monoglycerides, tsim cov khoom me me hu ua micelles.
Hais txog qhov no, txhais li cas los ntawm emulsification?
Emulsification (hauv kev zom zaub mov) Kev tawg ntawm cov roj globules hauv duodenum rau hauv cov me me, uas muab thaj chaw loj dua uas cov enzyme pancreatic lipase tuaj yeem ua rau zom cov rog rau hauv cov roj fatty acids thiab glycerol. Emulsification tau pab los ntawm qhov ua ntawm cov ntsev ntsev (saib cov kua tsib).
Qhov thib ob, cov kua tsib yog dab tsi thiab nws txoj haujlwm yog dab tsi? Cov kua tsib yog cov kua dej uas tsim thiab tso tawm los ntawm cov lub siab thiab khaws cia rau hauv cov gallbladder. Cov kua tsib pab nrog kev zom zaub mov. Nws zom cov rog rau hauv cov roj fatty acids, uas tuaj yeem coj mus rau hauv cov cev by cov txoj hnyuv.
Ib yam nkaus, tib neeg nug, lub luag haujlwm ntawm cov kua tsib hauv cov emulsification ntawm cov rog yog dab tsi?
Thaum digesting rog , bile ua ua li ib emulsifier kom tawg loj rog globules rau hauv me me emulsion me me. Kev siv ntawm no yog tias nws muab cov rog qhov loj dua qhov chaw uas cov lipase enzymes ( rog zom) tuaj yeem ua rau, uas ua rau nws ua cov txheej txheem sai dua thiab muaj txiaj ntsig.
Cov kua tsib ua tus emulsifier li cas?
Cov kua tsib raws li ib Emulsifier kua tsib ntsev ua raws li emulsifier vim lawv muaj lub taub hau hydrophilic (dej hlub) uas yog attracted rau dej molecules thiab ib tug hydrophobic (dej ntxub) tus Tsov tus tw yog attracted rau lipid molecules. Qhov no ua kom ntseeg tau tias cov lipid molecules tseem tawg thoob plaws hauv dej.

Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Dab tsi yog cov khoom siv hauv lub cev zom zaub mov thiab lawv lub luag haujlwm yog dab tsi?
Cov khoom siv hauv lub cev zom zaub mov suav nrog cov hniav, tus nplaig, cov qog ua kua qaub, daim siab, lub zais zis, thiab txiav txiav. Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais
Bile ntsev raws plab yog dab tsi?
Cov kua qaub kua qaub (BAD) yog ib yam mob uas cov kua tsib kua qaub tsis tau ua tiav hauv cov txheej txheem zom zaub mov, ua rau muaj cov tsos mob ntawm raws plab raws plab. Qhov mob no tseem tuaj yeem raug hu ua bile acid malabsorption (BAM). Txawm li cas los xij, kev tshawb fawb xyoo 2009 qhia tias qhov xwm txheej yuav tsis tas li vim yog malabsorption
Puas yog emulsification mechanical lossis tshuaj digestion?
Lub duodenum yog qhov uas feem ntau zom cov tshuaj lom. Bile emulsifies (tawg rau hauv cov khoom me me) lipid (cov rog), uas pab hauv kev zom zaub mov ntawm cov rog. Cov txiav txiav thiab cov qog ntshav ntawm cov hnyuv me zais cov zom zaub mov uas sib xyaw zom cov zom zaub mov nyuaj ua rau yooj yim dua
Qhov twg emulsification ntawm rog tshwm sim?
Fat emulsification yog cov txheej txheem ntawm kev nce thaj tsam ntawm cov rog hauv cov hnyuv me los ntawm kev muab lawv ua pawg me. Qhov no yog lub luag haujlwm ntawm cov kua tsib, cov kua uas tsim los ntawm lub siab thiab khaws cia rau hauv lub gallbladder. Kev zom cov rog tiag yog ua tiav los ntawm lipase, ib qho enzyme los ntawm tus txiav
