WebSep 1, 2024 · The two main secondary structures are the alpha helix and the anti-parallel beta-pleated sheet. There are other periodic conformations but the α-helix and β-pleated sheet are the most stable. A single polypeptide or … Like hemoglobin, myoglobin is a cytoplasmic protein that binds oxygen on a heme group. It harbors only one globulin group, whereas hemoglobin has four. Although its heme group is identical to those in Hb, Mb has a higher affinity for oxygen than does hemoglobin. This difference is related to its different role: whereas hemoglobin transports oxygen, myoglobin's function is to store oxygen.
