Qhov sib txawv tseem ceeb ntawm cov ntshav urea nitrogen thiab ntshav urea yog cov ntshav urea nitrogen ntsuas cov nitrogen hauv urea uas muaj nyob hauv cov ntshav, thaum cov ntshav urea yog qhov ntsuas uas txiav tag nrho cov urea hauv cov ntshav..
Thaum lub sijhawm cov metabolism hauv cov protein, degradation thiab tshem tawm cov seem ntawm cov metabolism hauv cov protein, tshwj xeeb tshaj yog cov nitrogenous Cheebtsam ntawm lub cev, feem ntau ua rau toxicity. Tam sim no, urea yog lub ntsiab nitrogenous excretory teeb meem nyob rau hauv cov tsiaj. Urea toxicity tus nqi yog qeeb qeeb dua piv rau ammonium. Lawv kuj muaj glycoprotein receptors uas tuaj yeem txheeb xyuas tus tswv tsev ntxiv los ntawm kev sib koom ua ke receptor-mediated binding.
Ntshav Urea Nitrogen yog dab tsi?
Ntshav urea nitrogen yog tus nqi ntawm urea nitrogen nyob hauv cov ntshav. Nws yog hais txog tus nqi ntawm nitrogen tam sim no hauv urea uas tawm mus rau cov ntshav. Urea yog qhov kawg ntawm nitrogenous excretory teeb meem tsim nyob rau hauv cov tsiaj. Yog li ntawd, cov ntsiab lus tseem ceeb ntawm urea yog nitrogen. Urea tsim tshwm sim los ntawm lub voj voog urea uas tshwm sim hauv daim siab feem ntau.
Daim duab 01: Nitrogen khib nyiab
Cov kev pom zoo ib txwm muaj ntawm cov ntshav urea nitrogen hauv tus neeg noj qab haus huv yog 6 mg / dL - 20 mg / dL. Txawm li cas los xij, cov teeb meem metabolic thiab kev hloov pauv kev noj haus tuaj yeem hloov cov ntshav urea nitrogen. Yog tias koj ua raws li kev noj zaub mov muaj protein ntau, koj tuaj yeem pom cov ntshav urea nitrogen ntau dua. Qhov no feem ntau yog los tiv thaiv kev sib sau ntawm nitrogen hauv cov kab ke tom qab noj zaub mov muaj protein ntau vim tias qhov sib xyaw ntawm nitrogen tuaj yeem ua rau muaj tshuaj lom.
Tsis tas li ntawd, nce catabolic tus nqi lossis cov leeg nqaij tawg, txo qis ntawm glomerular pom hauv lub raum thiab txo cov ntshav ntim tuaj yeem ua rau cov ntshav urea nitrogen nce siab. Hauv qhov sib piv, qhov qis ntawm cov ntshav urea nitrogen tuaj yeem pom thaum lub siab ua haujlwm tsis zoo, nce cov tshuaj tiv thaiv anabolic lossis tsim cov leeg nqaij. Yog li, qhov zoo tshaj plaws hauv cov menyuam yaus loj hlob, cov ntshav urea nitrogen qis dua piv rau cov neeg laus.
Ntshav Urea yog dab tsi?
Ntshav urea hais txog qhov concentration ntawm urea hauv cov ntshav. Urea yog lub ntsiab nitrogenous excretory teeb meem nyob rau hauv cov tsiaj, nrog rau tib neeg. Lawv muaj nitrogen ntau dua nyob rau hauv kev sib piv rau lwm cov nitrogenous khib nyiab tebchaw xws li uric acid thiab ammonium. Kev tsim cov urea tshwm sim hauv daim siab. Feem ntau, urea ntau lawm pib hauv daim siab mitochondria thiab ua tiav hauv daim siab cytosol.
Daim duab 02: Urea
Kev tsim cov urea pib nrog kev tsim cov carbamoyl phosphate. Carbamoyl phosphate nkag mus rau hauv lub voj voog urea lossis lub voj voog ornithine. Los ntawm ib tug series ntawm cov kauj ruam, urea yog generated. Kev pub dawb ntawm qhov thib ob nitrogen atom los tsim urea yuav siv qhov chaw nrog qhov sib ntxiv ntawm aspartate amino acid raws li qhov nruab nrab input.
ntshav urea nce ntxiv thaum cov leeg raug mob, tus nqi catabolic siab thiab noj zaub mov muaj protein ntau. Txawm li cas los xij, cov ntshav urea txo qis thaum lub siab puas tsuaj los yog siv tau rau hauv cov tshuaj tiv thaiv anabolic. Ntshav urea yog qhov ntsuas ntawm tus neeg noj qab haus huv. Hauv cov ntshav urea nitrogen, tus nqi lossis concentration ntawm nitrogen tsim urea raug kuaj tshwj xeeb.
Dab tsi zoo sib xws ntawm Ntshav Urea Nitrogen thiab Ntshav Urea?
- Ob leeg muab kev pom rau cov leeg-tsim tus nqi, cov leeg nqaij anabolism thiab catabolism.
- Tsis tas li ntawd, lawv kuj qhia cov leeg nqaij, txo cov protein noj lossis cov khoom noj tsis txaus.
- Kev noj zaub mov ntawm cov protein qhia pom qhov cuam tshuam ncaj qha rau ob qho tib si.
- Ob leeg ntsuas hauv mg/dL.
- Lawv muab lub tswv yim ntawm nitrogen metabolism, uas suav nrog cov tshuaj catabolic thiab anabolic.
- Kev tshwm sim thiab kev tswj ntawm lub voj voog urea yog qhov tseem ceeb rau ob qho kev ntsuas.
Qhov txawv ntawm Ntshav Urea Nitrogen thiab Ntshav Urea yog dab tsi?
Ntshav urea nitrogen thiab ntshav urea zoo sib xws hauv lawv lub luag haujlwm lom neeg thiab cov txheej txheem ntawm kev ua. Txawm li cas los xij, hauv cov ntshav urea nitrogen, cov ntsiab lus ntawm nitrogen hauv urea yog ntsuas thaum nyob rau hauv cov ntshav urea, tag nrho cov urea hauv cov ntshav yog ntsuas. Yog li, qhov no yog qhov sib txawv ntawm cov ntshav urea nitrogen thiab ntshav urea.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov ntshav urea nitrogen thiab ntshav urea.
Summary – Ntshav Urea Nitrogen vs Ntshav Urea
Qhov sib txawv tseem ceeb ntawm cov ntshav urea nitrogen thiab ntshav urea nyob ntawm seb hom kev ntsuas ntsuas hauv txhua qhov ntsuas. Hauv cov ntshav urea nitrogen, cov ntsiab lus nitrogen tam sim no raws li urea ntsuas. Hauv qhov sib piv, cov ntshav urea ntsuas tag nrho cov urea tam sim no hauv cov ntshav thaum tso tawm ntawm lub voj voog urea hauv lub siab. Ob leeg ntshav urea nitrogen thiab ntshav urea yog qhia txog cov protein metabolism uas tshwm sim hauv lub cev. Yog li, kev kuaj ntshav urea nitrogen thiab kuaj ntshav urea yog ib feem ntawm cov txheej txheem kuaj mob niaj hnub.
