👉 In physics and chemistry, a helix is a type of molecular structure in which each segment (a helix) is composed of a continuous chain of atoms. These segments are linked together to form an overall solid. Helical structures can be found in a wide range of materials, including proteins, enzymes, and even some types of crystals. Helices are named after the shape they take when viewed from above or below (the helix), rather than their position on the surface, as does the
