Oligosaccharides, tseem hu ua oligosaccharides, xa mus rau lub ntsiab lus dav dav rau cov khoom siv qis-polymer saccharides nrog cov saw ncaj los yog ceg ntoo uas tsim los ntawm 2-10 monosaccharide units txuas nrog glycosidic bonds. Nyob rau hauv xyoo tas los no, oligosaccharides tau nyiam ntau yam vim tias lawv yog cov pa roj carbon monoxide yooj yim tshaj plaws rau cov kab mob colonic ntxiv rau cov uas tsis yog starch polysaccharides. Tom qab noj cov carbohydrates, cov carbohydrates tsis zom hauv cov hnyuv thiab nkag mus rau hauv ileum thiab cecum hauv lub xeev qub. , nyob rau hauv txoj hnyuv, feem ntau los yog ib feem ntawm nws yuav siv tau los ntawm cov kab mob nyob rau hauv txoj hnyuv loj raws li ib tug substrate, uas ua rau ib tug txo nyob rau hauv pH thiab zus tau tej cov short-chain fatty acids, uas yuav txo tau cov kab mob pathogenic.

Raws li ib txwm muaj, tib neeg faib cov oligosaccharides rau hauv ob pawg raws li kev ua haujlwm sib txawv: cov oligosaccharides zoo tib yam thiab kev ua haujlwm oligosaccharides, ntawm cov oligosaccharides zoo tib yam (xws li sucrose, maltose, trehalose, cyclodextrin thiab Qab Zib, thiab lwm yam) tuaj yeem nqus tau los ntawm lub cev kom zom thiab zom. ua kom muaj zog, thaum ua haujlwm oligosaccharides tsis tuaj yeem nqus los ntawm lub cev, uas yog nyob rau hauv txoj kab nrog lub ntsiab lus ntawm prebiotics. Txhawb kev loj hlob ntawm bifidobacteria, txhim kho lub cev tiv thaiv kab mob thiab tiv thaiv kab mob, thiab txhawb kev loj hlob ntawm cov tsiaj. Txhim kho qhov zoo ntawm cov tsiaj nyeg thiab nqaij qaib cov khoom siv dej muaj qhov kev thov dav dav. Kev ua tiav kev ua haujlwm ntawm oligosaccharides suav nrog ntau dua 10 hom fructooligosaccharides, taum pauv oligosaccharides, galacto-oligosaccharides, isomalt oligosaccharides, xylo-oligosaccharides, mannose oligosaccharides, schitomalactosaccharides
