Tryptophan is an amino acid that has the molecular formula C11H12N2O2. To draw tryptophan, you will need to start with a pentagon, representing the 5-carbon sidechain of the molecule. Represented inside the pentagon will be a double bonded Oxygen (O=) and the Nitrogen (N). Next, draw the 4 hydrogen atoms that attach to the Nitrogen (H-N-H), and two Hydrogen atoms that attach to the Oxygen (H-O-H). Finally, draw two hydrogen atoms on the last Carbon and two Hydrogens on the middle Carbon atom, completing the molecule.
