Urea yog tsim nyob rau hauv lub siab thiab yog cov metabolite (cov khoom tawg) ntawm cov amino acids. Ammonium ions yog tsim los ntawm kev rhuav tshem cov amino acids. Qee qhov yog siv rau hauv biosynthesis ntawm nitrogen tebchaw. Tshaj ammonium ions raug hloov mus rau urea.
urea tsim nyob qhov twg thiab nws tawm hauv lub cev qhov twg?
Lub siab yog lub cev ua haujlwm hauv lub cev cov khoom pov tseg, piv txwv li, urea, uas yog tsim thaum cov amino acids ntau dhau lawm. Ntau dhau urea yog tshuaj lom yog li lub cev yuav tsum tau tshem tawm. Cov urea yog thauj los ntawm lub siab mus rau lub raum siv lub circulatory system.
Lub cev tsim urea li cas?
Thaum koj noj cov protein, lub cev zom lawv mus rau hauv cov amino acids. Ammonia yog tsim los ntawm cov amino acids tshuav, thiab nws yuav tsum raug tshem tawm ntawm lub cev. Lub siab tsim ntau yam tshuaj (enzymes) uas hloov ammonia rau hauv daim ntawv hu ua urea, uas lub cev tuaj yeem tshem tawm hauv cov zis.
Vim li cas urea tsim hauv lub cev thiab nws tsim nyob qhov twg?
Urea forms thaum noj zaub mov proteins ua cov amino acids tom qab kev zom. Lub siab zom cov amino acids ntau dhau los ua ammonia, tom qab ntawd hloov qhov no rau hauv urea, uas tsis muaj tshuaj lom hauv lub cev dua li ammonia.
YPuas yog urea ua los ntawm cov zis?
Urea yog ib qho tseem ceeb ntawm cov zis ntawm cov tsiaj txhu. Yog li nws tsis yog qhov xav tsis thoob tias qee cov neeg xav tias urea hauv tshuaj pleev ib ce los ntawm cov zis. Hauv kev lag luam tshuaj pleev ib ce, urea yog tsimsynthetically nyob rau hauv ib lub lab. Synthetic urea kuj feem ntau ntxiv rau cov khoom ci thiab cawv los pab nrog fermentation.
