helical
Helical is a term used to describe anything shaped like a helix, a three-dimensional curve obtained by rotating a line about a fixed axis while advancing along the axis. In everyday use it often refers to components, structures, or molecules that exhibit this spiraling form.
In geometry, the circular helix is the most common example, characterized by a constant radius r and
Natural and technological examples include the DNA double helix, a fundamental biological structure, and α-helix regions
Notes: not all spiral shapes are helices; a spiral lies in a plane, while a helix is
