The structure of Professor Kubasik's favorite peptide is shown above. the "sticks" are covalent bonds between atoms. The "dotted lines" are hydrogen bonds that help support 310 helical secondary structure. The synthetic effort in the lab is focussed on the preparation of analogues of this molecule and variants isotopically-enriched with 13C and 15N. A visualization of the left-to-right interconversion is here.
