Now you are ready to work with oligopeptides, or polymers composed of 3-20 amino acid residues. These polymers are linear; that is, each amino acid is linked to it's neighbor in a head-to-tail fashion rather than forming branched chains. You will be observing a 5mer in this tutorial. | Now you are ready to work with oligopeptides, or polymers composed of 3-20 amino acid residues.
