Hemoglobin and its allosteric mechanism regulating the binding of oxygen and other ligands served as a model of a huge number of molecular biological systems. The review focuses on the formal description of oxygen binding by hemoglobin and considers the main mathematical models ...

By comparing the experimental data so obtained with theoretically derived oxygen saturation curves for hemoglobin and isolated α-chains the values of the oxygen pairing energy and oxygen binding energy to hemoglobin molecule have been found to be 0.043 ± 0.004 and 0.60 ± 0.06 eV respectively.关键...

The oxygen binding hemoproteins hemoglobin (Hb), myoglobin (Mb), and cytochrome P-450 are important to the biological transport, storage, and metabolism of oxygen. Nevertheless the nature of the coordinate link between iron and dioxygen in these hemoproteins has not been defined at the atomic le...
Oxygen binding to isolated hemoglobin βSH chains exhibits heterotropic interactions with H+, inositol hexaphosphate and CO2 which implies different structures of the liganded and unliganded β chains. In order to find out if the dissociation behaviour of β4SH homotetramers is likewise linked to ...
The iron-containing hemoglobins (Hbs) are essential proteins to serve as oxygen transporters in the blood. Among various kinds of Hbs, the earthworm Hbs are the champions in carrying oxygen due to not only their large size but also the unusually high cooperativity of ligand binding. However, ...
Also explain what happens whenever hemoglobin arrives at the tissue. What part of aerobic respiration is directly effected by a lack of oxygen? What is the role of hemoglobin in red blood cells? What is the role of oxygen-binding proteins at the site of capillaries during respiration? What ...
