X-ray crystallography is a powerful technique used to determine the atomic and molecular structure of a crystal by measuring the angles and intensities of X-ray beams diffracted by the crystal lattice. This method has been pivotal in understanding the structures of complex molecules, including proteins and DNA, enabling advancements in fields like chemistry, biology, and materials science.

X-ray Crystallography

Atomic structure refers to the arrangement of subatomic particles—protons, neutrons, and electrons—within an atom, which determines its chemical properties and behavior. Understanding atomic structure is fundamental to fields like chemistry and physics, as it explains the periodic table, bonding, and the nature of matter itself.

Atomic Structure

Molecular structure refers to the three-dimensional arrangement of atoms within a molecule, which determines its chemical properties and reactivity. Understanding molecular structure is crucial for predicting how molecules interact in chemical reactions and in biological systems.

Molecular Structure

A crystal lattice is a highly ordered structure consisting of a repeating pattern of atoms, ions, or molecules in three-dimensional space, which gives rise to the unique properties of crystalline solids. Understanding the geometry and symmetry of crystal lattices is crucial for determining the material's physical properties, such as conductivity, strength, and optical characteristics.

Angles and intensities

Complex molecules are large, intricate structures composed of multiple atoms bonded together, playing crucial roles in biological processes and material science. Their complexity arises from the variety of atoms involved, the types of bonds between them, and the three-dimensional arrangements they form, enabling a vast range of functions and properties.

Complex Molecules

Proteins are complex macromolecules essential for various biological functions, including catalyzing metabolic reactions, DNA replication, and transporting molecules. They are composed of amino acids linked in a specific sequence, which determines their structure and function.

Proteins

DNA, or deoxyribonucleic acid, is the hereditary material in almost all living organisms, encoding the genetic instructions used in their development, functioning, growth, and reproduction. It is composed of two strands that coil around each other to form a double helix, carrying the genetic information in sequences of four types of nucleotides: adenine, thymine, cytosine, and guanine.
