Peptide bonds almost always assume the trans conformation: that in which successive alpha carbon atoms are on opposite sides of the peptide (C-N) bond joining them. | Peptide bonds almost always assume the trans conformation: that in which successive alpha carbon atoms are on opposite sides of the peptide (C-N) bond joining them. <scene name='User:Stephen_Mills/Sandbox_2_Peptide_tutorial/Argtyrtransamide/1'>Click here to show this trans bond.</scene> The exception are peptide bonds involving proline (when P is on the C-terminal side of the bond) - these can be trans or cis. | ||
