Hemoglobin, kuj sau hemoglobin, muaj protein ntau hauv cov ntshav ntawm cov tsiaj txhu- nyob rau hauv cov qe ntshav liab (erythrocytes) ntawm vertebrates -uas thauj oxygen mus rau cov ntaub so ntswg.
Hemoglobin nyob qhov twg thiab nws ua li cas?
Nws txoj haujlwm yog nqa oxygen hauv cov ntshav los ntawm lub ntswsmus rau lwm cov ntaub so ntswg hauv lub cev, txhawm rau muab cov hlwb nrog cov pa uas xav tau los ntawm lawv rau oxidative phosphorylation ntawm khoom noj khoom haus. Hemoglobin pom nyob rau hauv cov ntshav nyob rau hauv lub erythrocytes (cov qe ntshav liab).
nrhiav hemoglobin nyob qhov twg?
Hlau yog ib qho tseem ceeb rau kev tsim cov ntshav. Kwv yees li 70 feem pua ntawm koj lub cev hlau muaj nyob hauv cov qe ntshav liab ntawm koj cov ntshavhu ua hemoglobin thiab hauv cov leeg nqaij hu ua myoglobin. Hemoglobin yog qhov tseem ceeb rau kev xa cov pa oxygen hauv koj cov ntshav los ntawm lub ntsws mus rau cov ntaub so ntswg.
YPuas hemoglobin pom hauv erythrocytes?
Erythrocytes muaj protein hu ua hemoglobin, uas nqa oxygen los ntawm lub ntsws mus rau txhua qhov ntawm lub cev. Kev kuaj xyuas cov erythrocytes hauv cov ntshav feem ntau yog ib feem ntawm kev kuaj ntshav tag (CBC). Nws tuaj yeem siv los saib xyuas cov xwm txheej xws li ntshav ntshav, lub cev qhuav dej, tsis muaj zaub mov noj, thiab leukemia.
Kuv qib HB yuav tsum yog dab tsi?
Qhov ib txwm muaj rau hemoglobin yog: Rau cov txiv neej, 13.5 txog 17.5 grams ib deciliter. Rau cov poj niam, 12.0 mus rau 15.5 grams ib deciliter.
