Beta sheet alpha helix

In alpha helix, every backbone N-H group donates a hydrogen bond to the backbone C=O group, which is placed in four residues prior. In all of these cases, the formation of alpha helix precedes the appearance of beta sheet, which suggests that conversion from the simpler, more local helix structure to the often more convoluted sheet architecture during folding and pathogenic misfolding processes could be a unifying principle of general importance. PNAS papers by Linus Pauling, Robert Corey, and Herman Branson in the spring of 1951 proposed the alpha-helix and the beta-sheet, now known to form the backbones of tens of thousands of proteins. They deduced these fundamental building blocks from properties of small molecules, known both from cryst … The alpha helix is a polypeptide chain that is pole molded and wound in a spring-like structure, held by hydrogen bonds. On the other hand, Beta pleated sheets get made of beta strands associated along the side by at least two hydrogen bonds shaping a spine.

The cross-β-sheet structure is formed by association of β-sheets at a distance of The α-helix and β-sheet are the two main secondary structures and they are.
