Accessing Intra-molecular Connectivity Information in NextGen Archive: this figure displays a snippet from the NextGen Archive PDBx/mmCIF File and 3D representation of Hemoglobin, identified as the chemical component CCD HEM within PDB ID 3eqm. The ‘_chem_comp_bond’ and ‘_chem_comp_atom’ categories can be used for accessing detailed information about the bonds between atoms within a chemical component and the attributes of individual atoms in that component. Notably, the image highlights a specific instance where atom C3D forms a single bond with atoms C4D and CAD, and a double bond with atom C2D.
