This web content by Loren Dean Williams discusses the importance of molecular interactions, also known as noncovalent interactions, in various fields such as chemistry, biochemistry, and biophysics. These interactions play crucial roles in protein folding, drug design, material science, and more. Williams explores concepts such as non-bonding interactions, bonding interactions, the Periodic Table, and the behavior of biological macromolecules. He also delves into topics like short range repulsion, electrostatic interactions, ion pairs, and dipolar interactions. Williams sheds light on the complexity of molecular interactions and challenges conventional nomenclature, such as the term “van der Waals interaction.”
