The nature of the hydrogen bond
WebHydrogen bonds are also essential to maintaining the structural integrity of α-helix and β-sheet conformations of peptides and proteins. By causing the macromolecules to fold into a specific shape, the hydrogen bonds contribute to the apparition of their biochemical functions. Sign in to download full-size image Figure 14.5. WebHydrogen bond definition. A hydrogen bond can be explained as a weak bond created between a hydrogen atom and an electronegative element that has a lone pair to share with the hydrogen atom to create an electrostatic attraction between portions of the molecule of the two atoms. The nature of a hydrogen bond is either dipole-dipole type, ion ...
