three-dimensional structure

The three-dimensional (3D) structure of a molecule refers to the specific spatial arrangement of its atoms in space. It describes how atoms are positioned relative to each other, including angles and distances, creating the molecule’s shape. This 3D arrangement is crucial because it influences how molecules interact, bind to other molecules, and perform their functions in biological systems. Think of it as the molecule’s “shape” that determines its behavior, much like how a key’s shape allows it to fit into a lock. Understanding 3D structure helps scientists predict and manipulate how molecules work.
