#chemical_bond__bond  an electrical force linking atoms
  supertype:  #attractive_force__attraction  the force by which one object attracts another
  subtype:  #covalent_bond  a chemical bond that involves sharing a pair of electrons between atoms in a molecule
     subtype:  #coordinate_bond__dative_bond  a covalent bond in which both electrons are provided by one of the atoms
  subtype:  #cross-link__crosslink__crosslinkage  a side bond that links two adjacent chains of atoms in a complex molecule
  subtype:  #hydrogen_bond  a chemical bond consisting of a hydrogen atom between two electronegative atoms (e.g., oxygen or nitrogen) with one side be a covalent bond and the other being an ionic bond
  subtype:  #ionic_bond__ionicbond__electrovalent_bond__electrovalentbond__electrostatic_bond__electrostaticbond  a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion
  subtype:  #metallic_bond  a chemical bond in which electrons are shared over many nuclei and electronic conduction occurs
  subtype:  #peptide_bond__peptidebond__peptide_linkage__peptidelinkage  the primary linkage of all protein structures; the chemical bond between the carboxyl groups and amino groups that unites a peptide
