Two sib txawv globin chains (txhua tus nrog nws tus kheej heme molecule) ua ke los tsim hemoglobin.
Puas hemoglobin muaj 4 Globins?
Hemoglobin yog tsim los ntawm plaub subunits: ob subunits ntawm alpha-globin thiab ob subunits ntawm lwm hom globin.
Puas muaj pes tsawg subunits hauv hemoglobin?
Ib hemoglobin molecule yog tsim los ntawm plaub polypeptide chains, ob alpha chains ntawm 141 amino acid residues txhua thiab ob beta chains ntawm 146 amino acid residues txhua. Nyob rau hauv tag nrho cov molecule, plaub subunits yog nyob ze koom nrog, xws li nyob rau hauv ib tug peb-dimensional jigsaw puzzle, tsim ib tug tetramer.
YPuas muaj pes tsawg hemes hauv ib hemoglobin?
Lub hemoglobin molecule yog tsim los ntawm plaub polypeptide chains (Alpha 1, Beta 1, Alpha 2, Beta 2), noncovalently khi rau ib leeg. Muaj plaub heme- hlau complexes. Txhua lub saw tuav ib pawg heme uas muaj ib qho Fe++ atom.
Ntau npaum li cas cov hemoglobin muaj?
Txhua lub hemoglobin protein yog tsim los ntawm plaub subunits - ob alpha subunits thiab ob beta subunits - thiab txhua subunit muaj peev xwm los khi rau ib tug oxygen molecule ntawm nws pawg heme. Cov qauv kev tshawb fawb tau pom tias hemoglobin muaj nyob hauv ib qho ntawm ob qhov kev sib haum, hu ua T (taut) thiab R (so).

Pes tsawg labrums muaj pes tsawg leeg?
Muaj tsibcov khoom siv tseem ceeb uas tsim cov qhov ncauj qhov ncauj: Labrum - ib lub phaj zoo li sclerite uas ua rau lub ntsej muag los pab cov khoom noj. Mandibles - ob lub puab tsaig rau crushing los yog sib tsoo cov zaub mov. Lawv khiav ntawm ib sab mus rau sab, tsis nce thiab nqis .
