Dipeptide Amino Acid Model: Glycylglycine

Aspartame is a popular sugar substitute. Unlike other artificial sweeteners, aspartame is a dipeptide composed of two amino acids, phenylalanine (Phe) and aspartic acid (Asp), and the molecular formula C₁₄H₁₈N₂O₅.

Note the change in nitrogen atom geometry from tetrahedral to planar when forming a peptide bond. Use our free 3D Molecular Model Builder to list the parts of up to 10 amino acids. He will need to add a planar nitrogen for every peptide you want to build.
