A xenobiotic yog ib yam tshuaj muaj nyob rau hauv ib yam kab mob uas tsis tau tsim los yog xav kom muaj nyob rau hauv lub cev. Nws kuj tseem tuaj yeem npog cov tshuaj uas muaj nyob hauv ntau qhov ntau dua li niaj zaus.
Dab tsi yog xenobiotics thiab lawv cov piv txwv?
Xenobiotic yog ib lo lus siv los piav qhia tshuaj lom neeg txawv teb chaws rau tsiaj lub neejthiab yog li suav nrog cov piv txwv xws li cov khoom cog, tshuaj, tshuaj tua kab, tshuaj pleev ib ce, flavorings, fragrances, zaub mov additives, industrial chemicals thiab environmental pollutants.
Lub ntsiab lus ntawm xenobiotics yog dab tsi?
Xenobiotics tau txhais tias yogtshuaj uas cov kab mob raug nthuav tawm uas yog extrinsic rau cov metabolism hauv ib txwm ntawm cov kab mob. Yog tsis muaj cov metabolism, ntau xenobiotics yuav ncav cuag cov tshuaj lom. Feem ntau cov haujlwm metabolic hauv lub cell xav tau lub zog, cofactors, thiab enzymes thiaj li tshwm sim.
Dab tsi yog xenobiotic Vim li cas lawv rov ua dua?
Lub ntsiab lus ntawm Xenobiotic Cheebtsam:
Cov kab mob kuj tseem tuaj yeem ua rau ntau cov tshuaj xenobiotic, tab sis lawv tsis tuaj yeem degrade ntau lwm tus. Cov tebchaw uas tiv thaiv biodegradation thiab yog li nyob rau hauv ib puag ncig yog hu ua recalcitrant.
Vim li cas xenobiotics tseem ceeb?
Enzymes uas metabolize Xenobiotics tseem ceeb heev rau kev lag luam kws tshuaj vim tias lawv yog lub luag haujlwm rau kev tawg ntawmtshuaj. Ib yam li ntawd, Xenobiotic transporters kuj cuam tshuam rau lub sijhawm uas cov tshuaj muaj nyob hauv lub cev.
