- Select one of the following biological molecules
- Open 3DChem.
- Note: if 3DChem is not working, use CheMagic. In the search window (where it it says "Enter Jmol script or load commands here."), type load [compound name]. For example, load [Adenine]. Make sure to include brackets. Alternatively, you may choose a molecule from this index.
- View the molecule as a "Ball" or "ball & stick model. Make sure that hydrogens are visible.
- View the molecule in 3D and rotate in space.
- Turn on the labels to identify the atoms in each molecule
- Note: if unable to see labels, follow this color code: Carbon (black or gray), hydrogen (white), nitrogen (blue), sulfur (yellow), oxygen (red), phosphorus (orange)
- Record the number of each atom for the molecule in question in the form.
- Examine the raw data for the entire class.
- Examine the summary data for the entire class.
- What can you conclude about the composition of biological molecules?
- Are there significant differences between the composition of the various classes of biological molecules? If so, please explain
