The minimum structural unit (the dimer) that, when acted upon by space group symmetry operations, generates the full crystal structure.
The insulin dimer acts as the asymmetric unit within a crystal structure. It is a "giant" unit because it consists of hundreds of atoms. H21(1).mp4
The core topic is as a complex macromolecule. Deep Dive: Insulin Dimer as a Giant Asymmetric Unit The minimum structural unit (the dimer) that, when
Three of these dimer units are arranged around a threefold rotation axis to form a hexamer, which takes the shape of an oblate spheroid. The core topic is as a complex macromolecule
The video aids in understanding that lattice points in a diagram are distinct from the atomic positions themselves.

The video dv5020sup5.mp4 shows the "action of symmetry operations on the asymmetric unit," specifically how the atoms move, rotate, or translate. Key Concepts Illustrated in the Video
