WebThis hydrogen bonding pattern, repeated over many consecutive amino acid residues is what defines the alpha helix. Turn on the sidechains with this button: This button: shows the hydrogen bonds in the context of the original ribbon view. The following buttons: allow you to toggle H-bonds in any view. WebThe other type of secondary structure Pauling and Corey discovered is the ß sheet. Unlike the α helix, the ß sheet is formed by hydrogen bonds between protein strands, rather than within a strand. Some other characteristics of ß sheets are displayed below. The amino acids are more extended than in α helices, with 3.5 Å between adjacent ...

WebThe HBS motif mimics the hydrogen bonding pattern of an alpha-helix, with two hydrogen bond donors and two hydrogen bond acceptors arranged in a pattern that matches the hydrogen bonding pattern of a typical alpha-helix. This motif can be incorporated into short peptides via a ring-closing metathesis (RCM) reaction. WebThe alpha helix is a rod-like structure whose inner section is formed by a tightly coiled main chain, with its side chains extending outward in a helical array. The alpha helix structure …
