So we have the pentapeptide, so let's say the pentaglycine. So this is glycine one, glycine two, glycine three, glycine four, and the terminal glycine that we basically drew out. Now it's the nitrogen of this pentaglyne. So this is the pentaglycine shown here. It's this nitrogen that's going to form a bond with this carbon here. So this is an adjacent short peptide and the terminal amino acid E is the D alanine.
