Tryptophan / TRP / W (EnzDes coloring)

In the Foldit Lua interface, the functions structure.GetAminoAcid and structure.SetAminoAcid use lowercase "w" for tryptophan.

The double ring structure is known as indole, consisting of a six-sided benzene ring and a five-sided pyrrole. The pyrrole ring contains one nitrogen atom and four carbon atoms.
