in biomolecular structure description what is the normal data structure format

In biomolecular structure description, the normal data structure format is the Protein Data Bank (PDB) format. The PDB format is a standardized file format used to store and exchange biomolecular structure data, primarily for proteins and nucleic acids. It includes information about the atomic coordinates, chemical components, symmetry, and other relevant details of the biomolecule. The PDB format uses a combination of text-based and numerical data to represent the structure, allowing for easy storage, analysis, and visualization of biomolecular structures.
