CAN1958 has been working on a collagen-like solution and shared some images and comments in veteran chat.

[05:55] (CAN1958) About Collagen, the most consecutive hydrogen bonds I had was 8 in that Collagen Helix.
[06:08] (@phi16) I thought total number of hydrogen bonds was significant. I didn't think consecutive number of hydrogen bonds made a difference.
[06:09] (CAN1958) Just to say how long I could get it nicely done.
[06:09] (@phi16) I get it. Well done.
[06:11] (CAN1958) then a 9th out of 11 just didn't bound although it was symmetric to my eyes. :-)
[06:44] (@phi16) If you have a string of prolines and you make them all helices with the structure mode (2) does it form a proline helix?
[06:45] (@phi16) Do you have parallel proline helices?
[06:46] (CAN1958) Collagen picture show a sequence of PPGPPG not all PPPPPP.
[06:47] (CAN1958) Time for me to get some sleep :-)
[07:07] (CAN1958) Very low scoring structure, not worth doing it.
