the localized arrangement in space of regions of a biopolymer; often these types of structures are regular and recurring along one dimension, for example, the α-helix often found in proteins.

secondary structure

n.
The three-dimensional structure of the polypeptide backbone of a protein (such as alpha helix, beta sheet, and coil patterns), or the sugar-phosphate backbone of a nucleic acid (such as the double helix pattern of DNA).

To do so requires the ability to tell whether nucleotides are in a loop or a stem structure, which can be modeled using computer algorithms that develop secondary structures based on comparative or thermodynamic information (reviewed in Gardner & Giegerich 2004).
