Urea (NH2CONH2) yog ua los ntawm ammonia (NH3) thiab cov pa roj carbon dioxide (CO2) ntawm qhov siab thiab qhov kub siab. Cov khoom sib xyaw ntawm qhov sib xyaw no tau sib cais, feem ntau yog tshem tawm cov pa roj ammonia ua raws li cov pa roj carbon dioxide, kom tawm los urea ua.
Ib yam li ntawd, nws tau nug, koj ua ammonia urea li cas?
Kev sib xyaw ntawm cov pa CO2 thiab ammonia ntawm 240 barg tau hnov lus los ua ammonium carbamate. Qhov no yog cov tshuaj tiv thaiv exothermic, thiab cua sov tau rov qab los ntawm lub rhaub dej uas tsim cov pa. Thawj lub reactor ua tiav 78% hloov pauv cov pa roj carbon dioxide rau urea ua thiab cov kua yog ua kom huv.
Ib qho ntxiv, puas yog ammonia tawg rau hauv urea? Feem ntau ntawm peb cov nitrogen pov tseg los ntawm tawg ntawm cov amino acids. Qhov no tshwm sim los ntawm deamination. Kev deamination ntawm cov amino acids ua rau kev tsim khoom ntawm ammonia (NH npe3). Txawm li cas los xij, daim siab muaj cov kab ke ntawm cov kab mob thiab cov enzymes uas hloov pauv sai ammonia (thiab carbon dioxide) ua urea.
Hauv qhov no, ammonia thiab urea yog dab tsi?
Ammonia thiab urea . Ob leeg ammonia thiab urea yog cov muaj nitrogen sib xyaw. Ammonia yog qhov yooj yim tshaj plaws nitrogen muaj cov khoom sib xws nyob qhov twg urea ua yog derivative ntawm ammonia.
Urea yog dab tsi thiab nws tau tsim li cas?
Urea yog lawm tsim tawm thaum lub siab tawg cov protein lossis amino acids, thiab ammonia. Lub raum ces hloov lub urea ua ntshav mus rau cov zis. Nitrogen ntxiv raug ntiab tawm los ntawm lub cev dhau urea ua , thiab vim nws yog qhov yooj yim heev, nws yog txheej txheem ua tau zoo heev.

Qhov feem pua ntawm cov ntshav tau tsim los ntawm cov khoom tsim?
Cov qe ntshav no (uas tseem hu ua corpuscles lossis 'tsim cov ntsiab lus') suav nrog erythrocytes (cov qe ntshav liab, RBCs), leukocytes (cov qe ntshav dawb), thiab thrombocytes (platelets). Los ntawm qhov ntim, cov qe ntshav liab muaj li ntawm 45% ntawm cov ntshav tag nrho, cov ntshav plasma txog 54.3%, thiab cov qe dawb txog 0.7%
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Dab tsi yog ammonia thiab urea?
Ammonia thiab urea. Ob qho ammonia thiab urea yog cov muaj nitrogen sib xyaw. Ammonia yog qhov yooj yim tshaj plaws nitrogen uas muaj cov ntsiab lus uas urea yog ib qho derivative ntawm ammonia
Yuav ua li cas urea thiab uric acid tsim?
Urea thiab Uric Acid: Urea yog tsim los ntawm kev hloov pauv ntawm ammonia. Ammonia los ntawm kev zom cov amino acids uas tuaj yeem ua rau muaj kev phom sij yog tias muaj ammonia ntau hauv lub cev. Uric acid yog tsim los ntawm purines hauv cov khoom noj tom qab nws tau zom lawm
Yuav ua li cas secretion yog tsim los ntawm tag nrho cov unicellular exocrine qog?
QHOV CHAW UA HAUJ LWM ua rau tag nrho UNICELLULAR EXOCRINE GLANDS tsim? Txhua lub qog exocrine tsis sib xws zais cov protein mucin (uas dhau los ua hnoos qeev ntawm kev sib xyaw nrog dej)
