Hemoglobin properties before and after oxygenation

Property Deoxygenated Oxygenated
Fe-NO Hb, μM 3.7 ± 0.2 4.3 ± 0.5
SNO-Hb, μM 0.66 ± 0.08 0.56 ± 0.10
HbO2/total Hb, % 0.1 ± 0.2 97.2 ± 1.6
DeoxyHb/total Hb, % 99.4 ± 0.2 2.8 ± 1.6
MetHb/total Hb, % 0.6 ± 0.2 0.0 ± 0.0
β-Nitrosyl Hb*, % 50 ± 3 45 ± 6
Pentacoordinate α-nitrosyl Hb*, % 24 ± 3 0.3 ± 0.4

Total Hb = 5.2 ± 0.1 mM. Total NO/Hb = 0.00085 ± 0.00005. Data shown as average of 7 trials from 2 samples deoxygenated on different days ± SD. Percentage of hexacoordinate α-nitrosyl Hb is equal to that of 100% minus the sum of the β-nitrosyl Hb and pentacoordinate α-nitrosyl Hb.
