WebThe hypothesis behind the design of stabilized helices and helix mimetics is that these medium-sized molecules may pursue their targets with higher specificity because of a larger number of contacts. This protocol describes an optimized synthetic strategy for the preparation of stabilized α-helices that feature a carbon-carbon linkage in place ... WebProperties of the alpha-helix.The structure repeats itself every 5.4 Angstroms along the helix axis, ie we say that the alpha-helix has a pitch of 5.4 Angstr...

The dna double helix or duplex is held together by - Course Hero

WebThe alpha-helix structure is formed by a spiral coil of the polypeptide backbone, with hydrogen bonds between the carbonyl oxygen and the amide hydrogen of the backbone. This structure is described as "condensed" because it is a compact and tightly coiled shape, with the amino acid side chains projecting outward from the helix. WebFeb 15, 2010 · Hydrogen bonds provide most of the directional interactions that underpin protein folding, protein structure and molecular recognition. The core of most protein structures is composed of secondary structures such as α helix and β sheet. fmr96w
