N-terminus and C-terminus (Glu-Gly-Ala-Lys or EGAK)

Description
The amide bond formation leaves an amino group available on one end of the tetrapeptide and a carboxylate group on the other, called the
   N-terminus and  C-terminus, respectively.

The portion of each amino acid remaining in the chain is called
   an amino acid residue.

When specifying an amino acid residue in a peptide, the suffix –yl may be used (e.g., glycinyl, alanyl).
