Abubuwan da aka samo daga Hemoglobin

Abubuwan da suka samo asali daga haemoglobin sunadaran siffofin haemoglobin. Hemoglobin shine furotin a cikin jinin ja wanda ke motsa oxygen da carbon dioxide tsakanin huhu da kyallen takarda.

Munanan siffofin haemoglobin sun hada da:

• Carboxyhemoglobin: Wani nau'in haemoglobin ne wanda ya haɗu da carbon monoxide maimakon oxygen ko carbon dioxide. Yawanci wannan nau'in haemoglobin mara kyau yana hana motsi na al'ada na oxygen ta jini.
• Sulfhemoglobin: Wani nau'i ne mai saurin haemoglobin wanda ba zai iya ɗaukar oxygen ba. Zai iya haifar da wasu magunguna kamar su dapsone, metoclopramide, nitrates ko sulfonamides.
• Methemoglobin: Matsala da ke faruwa yayin da aka canza ƙarfe wanda yake ɓangare da haemoglobin don kada ya ɗauki iskar oxygen da kyau. Wasu kwayoyi da wasu mahaɗan kamar nitrites da aka gabatar cikin rarar jini na iya haifar da wannan matsalar.
