To further enhance the students' understanding of protein structure and function, the Visual Molecular Dynamics (VMD) tool was introduced in the next module, allowing them to browse and select protein crystal structures from the Protein Database Bank (PDB) () and investigate their 3D properties. Using the 6KPC protein as a model for visualization, students were able to explore the protein's hydrophobic and hydrophilic surfaces and residues, its various domains, and interactions between residues that form secondary structures, ultimately applying their newfound skills to investigate key characteristics of their assigned protein.
