It is now also an amino acid residue rather than an amino acid molecule. So, in the reaction above, glycine and alanine molecules are joined together to make a dipeptide molecule of glycylalanine which contains a glycine residue and an alanine residue.Zwitter Ions. Dipeptide Structure. As drawn, we have a nitrogen atom with three single bonds and, of course, a pair of electrons.he name of this dipeptide is glycylalanine. The-ine ending of the glycine is changed to-yl because it's-OH is lost in the dehydration reaction, making it a glycyl group. The glycyl group is attached to the alanine making glycylalanine.
