Molecular Interactions
Fundamental physical and chemical forces between molecules that govern their behavior, binding, and functional relationships in various systems.
Molecular Interactions
Molecular interactions form the foundation of all chemical and biological processes, representing the various forces and bonds that determine how molecules recognize, attract, or repel each other in space.
