Dear All,
by now we all have learned that right handed alpha-helices are more stable
than left handed ones. I have trouble to understand why it is so.
Is anybody able to explain it (e.g. on the Ramachandran plot).

Related question:
The unstable areas on the Ramachandran plot must correspond to sterical
hindrance between particular groups. How can we visualize that?
