Abstract
- Inositol hexaphosphate causes the shape of the oxidation-reduction equilibrium curve to become hyberbolic at acid pH values. 2. Inositol hexaphosphate also causes a decrease in the alkaline oxidation Bohr effect at these same pH values. 3. These results support the idea that inositol hexaphosphate causes methaemoglobin to take up the deoxyhaemoglobin quaternary structure at pH6.5.
摘要
- 在酸性pH值下，肌醇六磷酸会使氧化还原平衡曲线的形状变为双曲线。2. 在相同的pH值下，肌醇六磷酸还会导致碱性氧化玻尔效应减弱。3. 这些结果支持了这样一种观点，即在pH6.5时，肌醇六磷酸会使高铁血红蛋白呈现脱氧血红蛋白的四级结构。
