WebbTranscribed Image Text: 5. A histidine residue (His146) in Hb subunit has a side chain pka of 6.2 in the lung. Due to a conformational shift of Hb in the muscle, an amino acid moves into the close proximity of this histidine, shifting this His146 pka to 7.7: • a) what is the net charge of this His146 in the lung at pH 7.6 (show all the calculations)?

WebbHis146 has an abnormally high pKa because the salt bridge stabilizes the proton against dissociation. In the oxy form, however, the salt bridge simply cannot form, so the pKa falls to its normal value of about 6.5 As a result, at blood pH, His146 is largely unprotonated in oxy Hb; thus low pH favors protonation & thus the deoxy form Webb10 feb. 2024 · In a 3-year-old girl (patient S4) with hypomyelinating leukodystrophy-25 (HLD25; 620243), do Rosario et al.
