Backbone representations are simplified 3D depictions of proteins or nucleic acids that enable the polymer chain structure to be seen. In proteins, a simple backbone trace connects alpha carbons (balls) but the backbone trace line does not coincide with any of the covalent bonds in the main chain ().
