A hairpin is a special case of a turn, in which the direction of the protein backbone reverses and the flanking secondary structure elements interact. For example, the beta hairpin connects two hydrogen-bonded, antiparallel β-strands.

Hairpin technology is a winding technology for stators in electric motors and generators and is also used for traction applications in electric vehicles. In contrast to conventional winding technologies, the hairpin technology is based on solid, flat copper bars which are inserted into the stator stack.
A hairpin turn (also hairpin bend or hairpin corner) is a bend in a road with a very acute inner angle, making it necessary for an oncoming vehicle to turn about 180° to continue on the road. It is named for its resemblance to a bent metal hairpin.
Many roads around the world are known for their hairpin turns, sharp curves that require drivers to almost double back on their path. These turns, also known as switchbacks, help vehicles navigate steep terrains safely by allowing gradual ascent or descent.
The key α discoveries that improved -hairpin stabilities outside of protein β contexts have been sequences with good turn propensities, for example D-Pro-Gly (pG) (6), heterochiral P (7), and Aib-Gly.
Hairpin structures occur in pre-microRNA structures and most famously in transfer RNA, which contain three true stem-loops and one stem that meet in a cloverleaf pattern.

15 lis 2021 · A short hairpin RNA or small hairpin RNA (shRNA/Hairpin Vector) is an artificial RNA molecule possessing a tight hairpin turn that can be employed to silence target gene expression by the process of RNA interference (RNAi).
