A ball-and-stick model system representing alpha carbon positions and the peptide link between adjacent alpha carbons as modeling elements of two-piece sets. Each two-piece set comprises complementary ring rods and ball rods, the latter having a generally cylindrical body enlarged at one end to a sphere form with a slot through a portion of the enlargement. The ring rod also includes a generally cylindrical body with an enlarged end portion to fit snugly within the slot of the ball rod so that when they are fitted together they appear as a sphere with the cylindrical body portions extending outwardly therefrom. The cylindrical portions of adjacent model sets are united by a pintle and hole structure configured so that when fitted together a continuous cylindrical body extends between adjacent spheres. Scales and indices are arranged on the adjacent surfaces of the rod and ball elements to mark the angles or bend and torsion of consecutive amino acids in the molecule and the sets are color coded to identify particular amino acids in the molecule.
