How can I draw alpha helices in ChemDraw? I am trying to draw a polyisocyanopeptide with different kinds of monomeric units that intramolecularly interact with one another. However, I wanted to show these connections with its carbon backbone in the helix configuration.
An example of what I mean is shown below, taken from Kouwer et al (Nature 2013, 493 (7434), 651–655). How can I draw the alpha-helix as shown in red in ChemDraw (or any other program)?
I use ChemDraw Professional 19.1.1.32. If you follow  File&gt;Open Templates&gt;Advanced BioDraw, you will find the black helix that I have reoriented from horizontal to vertical. The red helix was enlarged and colored red. I hope this is of help.
