Hlau yog khaws cia, feem ntau hauv lub siab, xws li ferritin lossis hemosiderin. Ferritin yog cov protein uas muaj peev xwm ntawm 4500 hlau (III) ions rau ib qho protein molecule. Qhov no yog daim ntawv loj ntawm hlau cia. Yog hais tias lub peev xwm cia cov hlau nyob rau hauv ferritin yog ntau tshaj, ib tug complex ntawm hlau nrog phosphate thiab hydroxide forms.
koj cov ferritin khaws cia nyob qhov twg?
Ferritin muaj nyob hauv ntau lub cev hlwb, tab sis tshwj xeeb tshaj yog cov nyob hauv lub siab, spleen, pob txha pob txha, thiab hauv cov hlwb reticuloendothelial. Ferritin plays lub luag haujlwm tseem ceeb hauv kev nqus, khaws cia, thiab tso tawm cov hlau. Raws li cov ntaub ntawv khaws cia ntawm cov hlau, ferritin tseem nyob hauv cov ntaub so ntswg hauv lub cev kom txog thaum nws xav tau rau erythropoiesis.
Qhov twg yuav tsum ferritin qib?
Cov txiaj ntsig yuav txawv me ntsis ntawm cov chaw kuaj mob, tab sis feem ntau, cov qib ferritin ib txwm nyob ntawm 12 txog 300 nanograms ib milliliter ntawm cov ntshav (ng / mL) rau txiv neej thiab 12 rau 150 ng / ml rau poj niam.
Puas lub siab khaws ferritin?
Hlau yog khaws cia rau hauv daim siab hauv cov cores ntawm ferritin plhaubthiab raws li hemosiderin, ib qho khoom tsis sib haum tau los ntawm cov hlau nplua nuj ferritin. Hlau nyob rau hauv hepatocytes txhawb kev txhais ntawm ferritin mRNA thiab represses transcription ntawm DNA rau transferrin thiab transferrin receptors.
hlau khaws cia hauv lub cev nyob qhov twg?
Kwv yees li 70 feem pua ntawm koj lub cev hlau muaj nyob hauv cov qe ntshav liab ntawm koj cov ntshav hu uahemoglobin 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. Myoglobin, nyob rau hauv cov leeg nqaij, txais, khw muag khoom, thauj thiab tso oxygen.
