Web21 mei 2024 · Proteins fold into their native structures in an interplay driven by various non-covalent interactions such as hydrogen bonds, Van der Waal forces, hydrophobic, and ionic interactions. Thus, to understand a protein's features and functions at the molecular level, it is essential to characterize these interactions. WebIonic bonding. The structure of a protein can be stabilized by the force of attraction between amino acid side chains of opposite charge, such as the -NH 3+ side chain of Leu and the -CO 2- side chain of Asp.

"WebIonic bonds form when one atom has a much higher electronegativity than another. This causes the electronegative atom to pull electrons from the less electronegative atom, forming ions that stick to one another via electrostatic forces. Hydrogen doesn't form ionic bonds because it has a very average electronegativity of 2.1. " - Ionic bond in protein structure
