...bonds and water loss? I got a dumb biology worksheet about something we didn't really go over in class, and I don't know how to do this. If someone knows of an example on the Internet or can direct me to like a Paint drawing like on Photobucket, that would be cool. I already know the individual drawings of each of the three R-groups, I just don't know how to put them together and where the peptide bonds and water loss points are.

Voor drawing structures you can use ISIS Draw (free software). In this Program you will find templates that you can use for Peptides.
