• Alpha-‐Helix. – α-‐helix. The alpha helix is a secondary structure in proteins. This means that it results from the folding of a single amino acid chain.

Alpha helix secondary structure

Using the historic research of Frederick Sanger on insulin as a starting point, the complex The most common secondary structure is an alpha helix (Figure 9).

Illustration of amino, helical, helix - 174067513. The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a right hand-helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O group of the amino acid located four residues earlier along the protein sequence. The alpha helix is also called a classic Pauling–Corey–Branson α-helix.

(c)  A secondary structure of proteins that is a right-handed helix or coil, where each amino (N-H) group of the peptide backbone contributes a hydrogen bond to the carbonyl(C=O) group of the amino acid four residues N-terminal to it (n-4). It is the most common type of secondary structure. (Helical parameters for various secondary structures). See also Petsko&Ringe fig.

The same type of bonding occurs with the beta helix, but this time the bonds are between strands not within one strand. The alpha helix is a polypeptide chain that is rod-shaped and coiled in a spring-like structure, held by hydrogen bonds. Beta pleated sheets are made of beta strands connected laterally by two or more hydrogen bonds forming a backbone.

An alpha helix is a type of secondary structure, i.e. a description of how the main chain of a protein is arranged in space. It is a repetitive regular secondary structure (just like the beta strand), i.e. all residues have similar conformation and hydrogen bonding, and it can be of arbitrary length.

Aug 5, 2019 We showed that the secondary structure of the Puf proteins was not destroyed upon contact with the QDs. We demonstrated that these 

Secondary structures are short regions of ordered structure arising from folding of the protein chain.
