WebApr 13, 2024 · As hemoglobin is a tetrameric protein, each molecule has four binding sites for oxygen, and it is well-known that the binding of the first oxygen molecule enhances the … Hemoglobin has a quaternary structure characteristic of many multi-subunit globular proteins. Most of the amino acids in hemoglobin form alpha helices, and these helices are connected by short non-helical segments. Hydrogen bonds stabilize the helical sections inside this protein, causing attractions within the molecule, which then causes each polypeptide chain to fold into a specific …
