The
carbohydrate community has decided on a standard symbol representation for
carbohydrates. The
article is here, and the webpage is
here. Our group has created a
3D version of the symbols within the software VMD. Here's a
video showing both versions. We have also worked with David Sehnal to implement this into LiteMol,
here is an example. I wanted to reach out and see if you are interested to implement this representation within Chimera? We can discuss the details if so.
