This is a Java applet displaying a helical peptide sequence in the helix wheel
view or in the side view in which
the side chain interactions (e.g. i,i+4 or i,i+3) can be easily observed.
Hydrophobic amino acids are shown in red, hydrophilic amino acid are shown in green.
Is is possible to build an alpha-helix (100 degrees par residue) or a 3-10 helix (120 degrees per residue).
This applet is still in construction, the next version will allow a choice for amino acid colour codes. It is not currently possible to print the picture, except from a SGI.
