Section 4: Very short proteins are referred to as peptides. Below is a chemical diagram for the four amino acid peptide Arg-Cys-Thr-Asp. Clearly label on this diagram the: a) the peptide bond between each of these amino acids b) carboxy end of the peptide c) amino end of the peptide d) the alpha carbon of each amino acid e) circle the side chain (R group) of the Thr amino acid f) circle the side chain (R group) of the Asp amino acid.
