Concept Introduction:

A peptide bond is an amide bond. A dipeptide contains two amino acids linked by a peptide bond.

It is formed among amino group of one amino acid; the carboxyl group of the other amino acid.

The peptide structures are written, such that the amino group is at the left side and the carboxyl group is at the right side.

The left end of the peptide is called the N terminus and the right end is called the C terminus.
