WebR form: The binding of oxygen to hemoglobin causes the rupture of some of the ionic bonds and hydrogen bonds between the αβ dimers. This leads to a structure called the “R,” or relaxed form, in which the polypeptide chains have more freedom of movement . The R form is the high oxygen-affinity form of hemoglobin; Confirmation of Haemoglobin WebRobert J. Ouellette, J. David Rawn, in Principles of Organic Chemistry, 2015 Quaternary Structure. The quaternary structure of a protein is the association of several protein chains or subunits into a closely packed arrangement. Each of the subunits has its own primary, secondary, and tertiary structure. The subunits are held together by hydrogen …

WebHaemoglobin (Hb) is a type of globular protein present in red blood cells (RBCs), which transports oxygen in our body through blood. It is a tetrameric protein and contains the heme prosthetic group attached to each subunit. It is a respiratory pigment and helps in transporting oxygen as oxyhaemoglobin from the lungs to different parts of the body. WebIn an oxygenated state, the iron atom is bound to the oxygen molecule via ionic attractions like dipole forces. So, the correct answer is 'Ionic bond'. Was this answer helpful? イラレcs6 対応os
