Tertiary structure is formed by the packing of protein secondary structure elements into compact globular units called protein domains.

The open mouth was big enough to swallow a ship twenty times the size of Voyager, and the interior of the cylindrical framework was lumpy with globular units, deflector dishes and emitter grids.
