A tsis muaj zog acid tsim hauv cov qe ntshav liab thaum hydrogen ions ua ke nrog hemoglobin.
Puas yog ntshav tsis muaj kua qaub?
Cov kua qaub lossis alkalinity ntawm cov tshuaj, suav nrog cov ntshav, qhia ntawm pH nplai. Cov pH nplai, thaj tsam ntawm 0 (muaj zog acidic) txog 14 (muaj zog yooj yim lossis alkaline). Ib qho pH ntawm 7.0, nyob nruab nrab ntawm qhov ntsuas no, yog nruab nrab. Ntshav yog ib txwm me ntsis yooj yim, nrog ib txwm pH thaj tsam ntawm 7.35 txog 7.45.
HB Puas yog lub hauv paus lossis acid?
Thaum peb sawv cev rau ib qho acid hauv cov tshuaj tiv thaiv, peb feem ntau siv ib qho luv luv HA (los yog HB) qhov twg H yog cov proton uas tawm hauv cov tshuaj tiv thaiv nrog cov hauv paus thiab A (los yog B) yog lwm hom. Ntu, A lossis B tuaj yeem nruab nrab lossis tuaj yeem raug them. Ib feem, tsis muaj H yog lub hauv paus conjugate ntawm daim ntawv nrog H.
YPuas hemoglobin tsis yog?
Cov ntshav tseem ceeb tshaj plaws ntawm cov ntshav yog hemoglobin. Yog li, Harper (1967), Guyton (1968), Slonim A. Hamilton (1976) thiab lwm tus kws sau ntawv ntseeg tias nws suav txog 50-60 feem pua ntawm tag nrho cov ntshav tsis muaj peev xwm.
ntshav ua li cas thiaj tsis pab?
Tib neeg cov ntshav muaj cov tsis muaj carbonic acid (H 2 CO 3) thiab bicarbonate anion (HCO 3 -) txhawm rau khaws cov ntshav pH ntawm 7.35 txog 7.45, raws li tus nqi siab dua 7.8 lossis qis dua 6.8 tuaj yeem ua tau. tuag. Nyob rau hauv no tsis, hydronium thiab bicarbonate anion nyob rau hauv equilibrium nrog carbonic acid.
