In a beta sheet, the main chain, called the beta strand, is fully extended rather than tightly coiled, and the side chains of adjacent amino acids point in opposite … WebSecondary protein structure is the folding of the polypeptide chain to form alpha helices and beta sheets (Figure 1).Alpha helices are polypeptide chains that are held together by interactions within the chains, whereas beta-sheets are formed by different parts of the chain lining up with one another. Also, beta sheets can be parallel or antiparallel, meaning … 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. optimus medical group san francisco
