Composition of Biological Molecules

Directions

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.
