Triple-helix structure

WebJul 29, 2024 · Triple Helix DNA Occasionally, DNA even comes in the form of a triple helix! In this rare genetic structure, the third strand winds around the central double helix in the larger spaces left by the original staircase shape. A third strand of DNA (pink) can sometimes be found in the groove between the standard double helix (green). WebThese triple-helical molecules are then further organised into bundles of collagen fibrils. This high degree of organisation explains why collagen has superior mechanical properties, and why it is primed to provide structure and support to many of the body’s tissues. When collagen is hydrolysed under heat, the triple-helix unwinds and the ...

WebJul 20, 2024 · Collagen type I is usually found in the heterotrimer α1 2 α2 (a triple helix of two α1 chains and one α2 chain), but is also found in the α1 3 homotrimer (three α1 chains) in fetal tissues ... A triple helix is named such because it is made up of three separate helices. Each of these helices shares the same axis, but they do not take up the same space because each helix is translated angularly around the axis. Generally, the identity of a triple helix depends on the type of helices that make it up. For example: a triple helix made of three strands of collagen protein is a collagen triple helix, and a triple helix made of three strands of DNA is a DNA triple helix.
