== Ways of representing protein structure == | == Ways of representing protein structure == | ||
Protein structures can be displayed in many different ways. In <scene name='57/575866/Spacefill_segment/1'>spacefilling</scene> models, all of the non-hydrogen atoms are shown as spheres with their van der Waals radii. In the <scene name='57/575866/Ball_and_stick_segment/1'>ball and stick</scene> model, the atoms are shown as smaller balls, connected by sticks; this is further simplified in the <scene name='57/575866/Stick_segment/1'>stick</scene> model, which only shows the bonds between atoms. <scene name='57/575866/Backbone/2'>Backbone</scene> shows only the N-Calpha-C=O repeating unit; the <scene name='57/575866/Cartoon/1'>cartoon</scene> representation shows the secondary structures. | |||
'''Questions based upon these scenes:''' | |||
Which of these representations would be best for showing... | |||
--the secondary structures present in a molecule? | |||
--Channels, holes, or pockets in a protein? | |||
--Residues in the active site of an enzyme? | |||
Explain your answers. | |||
