_chem_comp_atom.atom_id

Name:
'_chem_comp_atom.atom_id'

Definition:

   The value of _chem_comp_atom.atom_id must uniquely identify
   each atom in each monomer in the CHEM_COMP_ATOM list.

   The atom identifiers need not be unique over all atoms in the
   data block; they need only be unique for each atom in a
   component.

   Note that this item need not be a number; it can be any unique
   identifier.

Type: atcode
