in biomolecular structure description what is the normal data structure format string graph

In biomolecular structure description, the normal data structure format is typically a graph. Biomolecular structures, such as proteins, nucleic acids, and carbohydrates, are often represented using graph-based models. These models capture the connectivity and spatial arrangement of atoms and residues within the molecule.

In these graph representations, atoms are represented as nodes, and the chemical bonds between atoms are represented as edges. Additional information, such as atom types, bond types, and spatial coordinates, can be associated with the nodes and edges of the graph.

Graph-based data structures provide a flexible and efficient way to describe the complex and hierarchical nature of biomolecular structures. They enable various computational analyses and simulations, such as protein folding, docking, and molecular dynamics simulations.
