Hey! Just build the peptid, click 1 atom, then now use the alternative under build called framgnet, click what you like to add.
Here is two amino acids imported on each other, both with a bromine group, and lastly a cyclo pentante on the lower residual, closing both of the Amino acids in:) just for the fun look of it :)
Cyclopenate in Pink + Bromine in red.
It worked..... thanks
I'll see for the assembling part
Thanks once again
Anytime :)
Yeah that part is harder, and after talking to some colleges we would recommend a graphical designer, not engineers in biochemistry hehe
Best of luck!
