Urea: nws yog dab tsi, thiab ua li cas nws hais tias, qhov kev nce los yog txo nyob rau hauv cov ntshav

Tom qab tau txais daim ntawv nrog luam biochemical ntshav kuaj, nws yog ua tau los xyuas txog cov qhia "urea" nyob rau ntawd. "Yuav ua li cas yog nws?" - nug cov neeg mob. Niaj hnub nimno pab kiag li lawm-gemanalizatory ua ntshav mus kuaj, thiab txiav laij cov tau kuj qhia tau tias ntau zog los tsis hauv daim duab. Nws yog tsis xav tsis thoob hais tias tus foundations ntawm threatening inscriptions hais tias muaj yog ib co kev hloov uas scares neeg. "Kuv muaj cov ntshav poob los yog muaj zog urea. Yuav ua li cas nws yog li cas thiab nws threatens rau kuv? "- cov lus nug no suab nyob rau hauv lub kws kho mob lub chaw ua hauj lwm thiab tsav mus rau hauv qhov browser nrhiav bar. Wb sim kom paub tseeb.

Yuav ua li cas hom ntawm tshuaj: urea

Sib nws yog ib tug diamide ntawm carbonic acid. Nyob rau hauv tib neeg thiab tsiaj, qhov no tshuaj - ib qho ntawm qhov kawg khoom ntawm lub disintegration ntawm protein molecules. Complex proteins uas tawg mus rau hauv yooj yim, thiab ces los lub thib ob tig. Raws li ib tug tshwm sim, lub cev tau txais amino acids, uas muaj protein molecules. Tom qab qhov kawg plab zom mov generated lom tshuaj - ammonia. Nws coj cov hlab ntsha mus rau lub siab nyob qhov twg los ntawm txoj kev ob peb biochemical kev tig cev urea tsim los ntawm nws. Yuav ua li cas yog nws, tam sim no nws yog ib qhov tseeb.

Vim li cas peb txiav txim cov ntsiab lus ntawm urea nyob rau hauv cov ntshav?

Yuav ua li cas yog mus nrog cov khoom no? Los yog rau cov uas nws yog tsis siv nyob rau hauv lub cev thiab yuav tsum tau muab tshem tawm kiag los ntawm lub cev. Muab nws yog tas los ntawm ob lub raum nyob rau hauv cov zis.

Yog li, rau cov kws kho mob ua biochemical tsom xam ntawm cov ntshav, urea, los yog ntau tshaj precisely, nws npaum li cas - ib tug qhia ntawm lub zoo kev ntsuam xyuas ntawm lub raum muaj nuj nqi, lawv haumxeeb muaj peev xwm. Nws yog tseem tau mus kov tshawb thiab siab muaj nuj nqi, uas synthesizes cov organic molecules. Tab sis rau li cas lub hom phiaj nyob rau hauv ib daim ntawm cov ntshav mus kuaj muaj yog ib tug kab "urea". Yuav ua li cas yog nws, thiab yog dab tsi rau tus kws kho mob txiav txim seb yuav ua li cas npaum li cas nws nyob rau hauv peb lub cev, peb to taub. Tam sim no nws yog tsim nyog los tham txog dab tsi nws txhais tau hais tias sib txawv nyob rau hauv cov ntshav qhov tseem ceeb ntawm lub cev qhov tseem ceeb.

Tus nqi hloov cov ntsiab lus ntawm cov tshuaj yeeb dej caw

Nce urea nyob rau hauv cov ntshav yog cai nyob:

• uas tsis nyob rau hauv cov khoom noj (muaj protein ntau kom tsawg);
• Enhanced kab mob thiab ib ce muaj zog nyuaj siab nrog disintegration cov nqaijrog (hlav, mob mob, endocrine ntshawv siab);
• cov kab mob ntawm lub raum, lub plawv, cov hlab ntsha (pyelonephritis, glomerulonephritis, amyloidosis, lub plawv tsis ua hauj lwm, lub raum vascular anomalies).

Txo tus nqi ntawm cov urea nyob rau hauv cov ntshav no tshwm sim thaum:

• vegeterianstve (tsawg protein tsawg);
• hepatic txhab (tus kab mob siab, mob npuas paug, hlav);
• kab mob nrog impaired plab hnyuv zom cov zaub mov uas muaj protein ntau thiab cov amino acid tsawg (o, postoperative tej yam kev mob, cab txhab);
• pancreatic kab mob nrog poob feem ntawm enzymes (pancreatitis).

Nyob rau hauv tag nrho, nws yog tseeb hais tias tus nqi ntawm "urea" siv rau kev ntsuam xyuas raum muaj nuj nqi thiab lub siab, tab sis txawm yog hais tias tus kuaj abnormality nyob rau hauv cov ntshav, tsis txhob ntshai. Nws yog tsim nyog los xyuas tus nqi ntawm cov urea nyob rau hauv cov zis, raws li zoo raws li mloog mus rau lub kev ntsuam xyuas ntawm lwm yam kev ntsuas ntawm chaw ua hauj lwm ntawm sab hauv nruab nrog cev.
