Question

Are there applications of group theory (take it broadly: representation theory, Lie algs., q-groups, whatever ... ) to math. biology ?

I am in particular interested about applications to pharmacology (in particular pharmacokinetics, pharmacodynamics ) ? But would be happy to hear about any applications to biology/pharmacology.

PS
