Crystal Structure
Crystal Structure — The three-dimensional arrangement of atoms within a crystallized molecule, determined by X-ray diffraction and essential for structure-based peptide design.
What Is a Crystal Structure?
A crystal structure is the atomic-resolution 3D arrangement of a peptide determined by X-ray crystallography. Crystal structures reveal peptide conformation, hydrogen bonding networks, and binding interactions with receptors at 1-3 Å resolution, providing the structural basis for rational peptide design.
