Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the
C-2-C-3 bond.
1. Edit the Newman projection on the canvas.
2. Replace the appropriate hydrogens with the appropriate -CH3 or other groups.
3. If you need to start over, Undo or choose a Newman projection from the Templates toolbar
(bottom).
Important: Never delete the hydrogen atoms or bonds directly attached to the template, and do not move
them by dragging or dropping them. That will break the projections structures. Only replace them!
