You may be familiar with the double helix structure that DNA adopts. A helix is an example of secondary structure. Proteins can adopt a helical structure as well. This structure is called the alpha helix. Attractive forces between the different atoms cause them to want to be next to each other.

A neural network is able to arrange a set of proteins depending on their ultraviolet circular dichroism spectra in a completely unsupervised learning process. Analysis of the proteinotopic map reveals that the network extracts the main secondary structure features even with the small number of examples used.

MOTIVATION: Secondary structure predictions based on the properties of individual residues, and sometimes on local interactions, usually fail to exceed 65% efficiency. Therefore, non-local, long-range interactions seem to be a significant cause of this limitation.

Secondary Structure of Proteins; The term secondary structure refers to the locally coiled regions of the helical structure. The secondary structure and various helices which are characteristic of it marks the start of what the protein requires to remain stable and perform its desired function.
