Summary

edit
Description "Stick" image of the cyclol-6 molecule proposed by Dorothy Maud Wrinch in 1936 (Nature, 137, 411-412). This molecule can be considered a cyclic hexapeptide in which three peptide groups have fused by cyclol reactions into a central ring. Note that the three outer (unfused) peptide groups are not planar, but have dihedral angle ω=60°. The three red atoms in the central ring represent the hydroxyl groups formed by the cyclol reactions, whereas the three outer red atoms represent the oxygens of carbonyl groups. The PDB file was constructed by me using my own software and visualized using PyMol; both were done on 20 October 2006. I hereby release this image under the GFDL.
