alpha helix
This term is a technical designation used exclusively within biochemistry and structural biology. It describes a specific geometric arrangement of amino acids that is critical for the folding and function of proteins. Because it refers to a precise chemical structure, it is used in a descriptive, scientific register rather than a general or metaphorical one.
As a countable noun, it refers to a specific structural motif. In scientific literature, it is frequently paired with adjectives such as "amphipathic" or "transmembrane" to specify the chemical properties or the cellular location of the helix.
