molecular structures
Atoms' spatial arrangements
Molecular structures are the three-dimensional arrangements of atoms within molecules—how atoms bond together and orient in space.
Chemistry and biology depend on understanding these configurations, since a molecule's shape determines its properties and behavior: The drug's effectiveness depends on its molecular structure matching the receptor.
The term often appears in discussions of proteins, DNA, and synthetic compounds.
