Set of three congruent geometrical helices with the same axis
This article is about the biophysical phenomenon. For the management concept, see triple helix model of innovation.
The collagen triple helix is a triple helix formed from three separate protein helices, spiraling around the same axis.
In the fields of geometry and biochemistry, a triple helix (pl.: triple helices) is a set of three congruent geometrical helices with the same axis, differing by a translation along the axis. This means that each of the helices keeps the same distance from the central axis. As with a single helix, a triple helix may be characterized by its pitch, diameter, and handedness. Examples of triple helices include triplex DNA,[1] triplex RNA,[2] the collagen helix,[3] and collagen-like proteins.
