Peptide bond formation. : . α-carboxyl group of one amino acid (with side chain R1) forms a covalent peptide bond with α-amino group of another amino acid . ( . with the side chain R2) by removal of a molecule of water. The result is : Dipeptide ( i.e. Two amino acids linked by one peptide bond). By the same way, the dipeptide can then forms a second peptide bond with a third amino acid (with side chain R3) to give . GLYCINE. Glycine is the . simplest . amino acid.

Proline differs from other amino acids in that its side chain and amino N form a rigid, five -member red ring structure (Figure 5). Proline, then, has a secondary (rather than a primary) amino group. It is frequently referred to as an “. Class- . Bsc bioscience 6. th. semester. Section – . D. Introduction.
