WebSep 20, 2024 · Hemoglobin is structurally similar to myoglobin, used to store oxygen in muscles. The quaternary structure of a hemoglobin molecule includes four tertiary structure protein chains, which are all alpha helices. Individually, each alpha helix is a secondary polypeptide structure made of amino acid chains. Does hemoglobin quaternary structure … Web(a) Tertiary/Quaternary Structure 1. Each α and β subunit shares a conserved tertiary structure composed mostly of α helices. 2. Two dimers ( α1β1 and α2β2) associate to form the tetramer. 3. When fully deoxygenated, i.e. all monomers lacking bound oxygen, multiple salt bridges (ionic bonds) are involved in stabilizing the tetramer's "Tense" state. girnar technologies
