Hemoglobin kinetics and the effect of organic phosphates.
A kinetic model based on allosteric mechanisms of cooperativity fits the experimentally observed phosphate dependence of hemoglobin reactions. Subunit inequivalence is found to be important in analyzing hemoglobin kinetics. The observed increase in the rate of deoxygenation in the presence of organic phosphates is primarily related to the increased rate of dissociation of the second oxygen mole...
متن کاملThe Titration of Organic Acids in Urine
The simple titration method for the determination of organic acids in urine, described by Van Slyke and Palmer (I), has in many circumstances proved satisfactory. A more extended employment of the method to determine organic acids in pathological urines has brought to light limitations and sources of error which need consideration. The organic acids present in urine, both free and as salts, are...
متن کاملThe interaction between erythrocyte organic phosphates, magnesium ion, and hemoglobin.
Oxygen equilibria have been used to study the interaction between red cell organic phosphates, magnesium ion, and hemoglobin. We measured the oxygen affinity of hemoglobin solutions containing either 2,3-diphosphoglycerate (2,3-DPG) or ATP and varying concentrations of magnesium ion at lo”, ZO”, and 30”. Deoxyhemoglobin and Mg2f were competitors, binding reciprocally with the organic phosphates...
