SECONDARY STRUCTURES OF PROTEINS 1: HELICES
A polypeptides secondary structure is defined by the local conformation of its main chain. There are two major types of regular polypeptide main chain conformation: helices and sheets. There are also regular turn structures that often connect elements of secondary structure.


Helices
Helices are the most striking elements of secondary structure.
