It was found that zinc chloride added to normal and SCD blood to a final concentration of 1.5 脳 10鈭 3 M caused a left-shift of the blood oxygen affinity curve (increased oxygen affinity) varying from 1.5 to 3.5 mm Hg change in half saturation (p50). This curve shifting property has ...
The oxygen-carrying properties of the blood had been shown to be determined by oxygen capacity, oxygen saturation, and oxygen affinity, the latter expressed by a graph relating oxygen saturation (S[O.sub.2]) to oxygen tension (P[O.sub.2]), the oxygen saturation curve. Although these quanti...

Oxygen affinity to haemoglobin was first described by Bohr, Hasselbalch and Krogh (1904), who discovered the S-shaped form of the oxyhaemoglobin dissociation curve (ODC)8. Haemoglobin may exist in two alternative structures, the deoxy or T (tense) and the oxy or R (relaxed) structure. Effect...

The shape of the oxygen‐binding curve shows a strong temperature‐dependence, since the overall heat of the binding of oxygen to the low‐affinity state of the molecule is strongly exothermic and that to the high‐affinity state is very close to zero. The results outline the intramolecular ...
