Myoglobin has 8 alpha-helices

WebWhat are the alpha helices in myoglobin? Myoglobin contains eight segments of a helix, designated by the letters A through H, counting from the N-terminus. The helices provide a rigid structural framework for the heme pocket . The heme is wedged into a hydrophobic pocket between the E and F helices. HEMOGLOBIN AND MYOGLOBIN BIOCHEMISTRY WebMyoglobin has 8 alpha helices and a hydrophobic core. Myoglobin’s molecular weight is 16.7 kDa, and it is the primary oxygen-carrying pigment of muscle tissues. The binding of oxygen in myoglobin is different from the cooperative oxygen binding in hemoglobin, since positive collaboration is a property of multimeric/oligomeric proteins only.
