Determine the sequence of the segment by hovering over the residues taking time to consider the nature of their side chains and from which direction their side chains project from the backbone. All the Gly need to be on the same side of the peptide in order to construct the silk fiber. Labels describe how additional <scene name='Fibroins/Chain_a_2/1'>units of the hexapeptide</scene> are added to the ends of this peptide segment to produce the longer polypeptide. | Determine the sequence of the segment by hovering over the residues taking time to consider the nature of their side chains and from which direction their side chains project from the backbone.
