Figure 1

A general formula of a peptide molecule. This representation shows at least one peptide bond. R1, R2, and Rn represent side chains of n amino acid residues. With a loss of one molecule of water from two amino acids, one peptide bond (−CONH−) is formed. When n = 0 (i.e., the third amino acid residue does not exist), the peptide will be a dipeptide; when n = 1, the peptide will be a tripeptide; and so on.
