View1 shows a ribbon diagram, in gray, of the "Globin" (protein) portion of sperm whale deoxymyoglobin in which its eight helical segments, A through H, are displayed with two strands. Use the "zoom" slider to properly size the molecule in the viewer. Toggle the "ANIMATE" button to sequentially color these helices and their preceding nonhelical segments in rainbow order. You can see that the globin consists mostly of alpha helices; it has no beta sheets and its nonhelical segments mostly serve as links that connect the helices. Look down the barrel of some of the longer helices. Are they all straight? | View1 shows a ribbon diagram, in gray, of the "Globin" (protein) portion of sperm whale deoxymyoglobin in which its eight helical segments, A through H, are displayed with two strands.
