3D Structure Visualization

Definition

3D structure visualization refers to the techniques and tools used to create three-dimensional representations of biological macromolecules, such as proteins and nucleic acids. These visualizations allow researchers to understand the spatial arrangement of atoms, secondary structures, and overall shape, which are crucial for studying molecular interactions, functions, and dynamics. By providing a clearer view of complex biological entities, 3D structure visualization facilitates insights into how these molecules operate within biological systems.
