IiHemoglobin CAS:9008-02-0 Ixabiso lomenzi

Ukuthuthwa kweoksijini: Umsebenzi oyintloko we-hemoglobin kukubopha ioksijini emiphungeni kwaye uyithuthe iye kwizicubu zomzimba wonke. Oku kuqinisekisa ukuba iiseli zifumana ioksijini eziyidingayo ukuvelisa amandla kunye neenkqubo ezibalulekileyo.

Ukususwa kwekhabhoni diokside: I-hemoglobin ikwadlala indima ekuthwaleni ikhabhoni diokside, imveliso yenkunkuma yemetabolism yeseli, ukusuka kwizicubu ukuya emiphungeni ukuze ikhutshwe ngokuphefumla.

Ibhalansi ye-asidi: I-hemoglobin isebenza njenge-buffer, inceda ekulawuleni i-pH yegazi ngokuzibophelela kwii-ion ze-hydrogen ezingaphezulu (i-asidi) okanye ukuzikhulula xa igazi liba ne-alkaline kakhulu. Oku kubalulekile ekugcineni imisebenzi efanelekileyo yomzimba kunye nokuthintela i-acidosis okanye i-alkalosis.

Ukuxilongwa kweemeko zonyango: Ukulinganiswa kwamanqanaba e-hemoglobin ngovavanyo lwegazi kudla ngokwenziwa ukuze kuchongwe kwaye kujongwe iimeko ezahlukeneyo zonyango, kubandakanya i-anemia (amanqanaba aphantsi e-hemoglobin), i-polycythemia (amanqanaba aphezulu e-hemoglobin), kunye nezinye iingxaki zegazi.

Ukufunxa igazi: Ulwazi ngendima ye-hemoglobin ekuthuthweni kweoksijini luye lwasetyenziswa kwimidlalo ethile ngokusebenzisa umkhwa obizwa ngokuba yi-"blood doping." Abadlali bandisa amanqanaba abo e-hemoglobin ngokwenziwa ngokufaka iiseli ezibomvu zegazi ezongezelelweyo okanye ukusebenzisa izinto ezifana ne-erythropoietin (EPO) ukuphucula ukunyamezela nokusebenza. Nangona kunjalo, lo mkhwa awuvumelekanga kwimidlalo yokhuphiswano ngenxa yeengozi zempilo ezinokubakho.

Uphando nophuhliso: I-Hemoglobin kunye nolwakhiwo lwayo kuye kwafundwa ngokubanzi ukuze kuqondwe iimpawu zayo zokusebenza kunye nesiseko seemolekyuli zezifo ezahlukeneyo. Olu lwazi lube negalelo ekuphuhliseni iinkalo ezifana ne-genetics, i-biochemistry, kunye neyeza.
