Category chem_comp

Category Description

              Data items in the CHEM_COMP category give details about each
               of the chemical components from which the relevant chemical
               structures can be constructed, such as name, mass or charge.

               The related categories CHEM_COMP_ATOM, CHEM_COMP_BOND,
               CHEM_COMP_ANGLE etc. describe the detailed geometry of these
               chemical components.
