This video talks about the alpha helix structure of proteins.The α helix, a common structural motif of proteins, consists of a right-handed helix with a repe


Alpha-helices have 3.6 amino acid residues per turn, ie a helix 36 amino acids long would form 10 turns. The separation of residues along the helix axis is 5.4/ 3.6

Successive turns of the helix are linked by weak hydrogen bonds and the structure is much more stable than an untwisted polypeptide chain. Alpha helix and helix 3/10 are, in general, underrepresented around Asp residues involved in [Mn.sup.2+] coordination. Secondary structure preferences of [Mn.sup.2+] binding sites in bacterial proteins 2008-10-02 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. Each beta strand, or chain, is made of 3 to 10 amino acid residues. It is important to mention, that this α‐helix comprises the conserved θ 1 xxθ 2 xxθ 3 motif and has amphipathic character with residues Leu ‐17 (θ 1), Leu ‐14 (θ 2), Leu ‐11 (θ 3) and residues Glu ‐16, Glu ‐13 and Asp ‐10 representing the hydrophobic and negatively‐charged patches of the α‐helix, respectively (Figure 4 b and S3).

Therefore, the alpha helix, beta sheet and random coil regions of proteins and the double helix of nucleic acids have CD spectral signatures representative of their structures. Circular polarization-Wikipedia. The spherical core consists of an alpha helix and a beta sheet.

Myoglobin (Mb), and its evolutionary cousins, the α- and β-polypeptide chains of hemoglobin (Hb), exhibit unusually high percentages of α-helical structure (more than 70%). In an amphipathic α helix, one side of the helix contains mainly hydrophilic amino acids and the other side contains mainly hydrophobic amino acids.
