Kev nqus cov piam thaj yog electrogenic nyob rau hauv cov hnyuv me epithelium txoj kev loj rau kev thauj cov piam thaj los ntawm plab hnyuv lumen mus rau hauv enterocytes yog Na +/glucose cotransporter (SGLT1), txawm hais tias cov piam thaj thauj khoom hom 2 (GLUT2) kuj tuaj yeem ua lub luag haujlwm.
Yuav ua li cas thiaj nqus tau cov piam thaj?
Kev nqus cov piam thaj entails thauj los ntawm txoj hnyuv lumen, hla lub epithelium thiab mus rau hauv cov ntshav. Tus thauj khoom uas nqa cov piam thaj thiab galactose mus rau hauv lub enterocyte yog sodium-dependent hexose transporter, paub ntau yam ua raws li SGLUT-1.
Glucose absorbed hauv plab li cas?
Glucose yog absorbed los ntawm txoj hnyuv los ntawm a transepithelial thauj system pib ntawm apical membranelos ntawm cotransporter SGLT-1; Intracellular qabzib yog tom qab ntawd xav tias yuav kis thoob plaws basolateral membrane los ntawm GLUT2.
Puas qabzib nqus sai?
Ob lub qabzib thiab fructose tau nqus sai sai, nyob ntawm seb lwm cov khoom noj twg tau noj tib lub sijhawm. Piv txwv li, noj mov lossis zaub mov uas muaj cov protein thiab rog ua rau cov suab thaj nqus tau qeeb dua thaum noj ntawm lawv tus kheej.
Yuav ua li cas qeeb qhov nqus ntawm cov piam thaj?
Thaum soluble fibre cuam tshuam nrog dej nws tsim cov gel. Hauv daim ntawv gel no, lub plab zom mov, kev zom zaub mov thiab kev nqus cov piam thaj tau qeeb.
