Chemical Databases

[C Webster]

Does anyone know of a database of chemical structures for amino acids and the
like ? Specifically I'm looking for a picture of the amino acid tyrosine in 3D.
I have the rasmol package, are there any databases of files that can be loaded
into this package and then manipulated.

TIA
