Protein secondary structure origami by Brian C. Mahon, Ph.D.

1) Cut out the four strips with letters and remove waste paper from the printed amino acids

2) Line up letters on the loop structures with the letters at the ends of the strings of amino acids

3)Fan fold the page along the R-group positions

4) Prepare to cut between each string of amino acids

5) Snip!

6) Snip!

7) Snip!

8) Looks a polypeptide to me! But we are not done yet!

9) So many partial charges! So little time!

10) Hydrogen bonds to the rescue!
