Phenylalanine / PHE / F (EnzDes coloring)

Phenylalanine (PHE or F) is among the most hydrophobic of the amino acids. Its shape in Foldit is similar to that of tyrosine, but it lacks the "stick" on top. Also, unlike the pentagonal histidine, phenylalanine is hexagonal.

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