WebA helix(/ˈhiːlɪks/) is a shape like a corkscrewor spiral staircase. It is a type of smoothspace curvewith tangent linesat a constant angleto a fixed axis. Helices are important in biology, as the DNAmolecule is formed as two intertwined helices, and many proteinshave helical substructures, known as alpha helices. Web2 sep. 2024 · University of Chicago. Cooperativity plays an important role in the description of the helix–coil transition, which refers to the reversible transition of macromolecules between coil and extended helical structures. This phenomenon was observed by Paul Doty in the 1950s for the conversion of polypeptides between a coil and α-helical form, 2 ...
