Structural biology being a sub-discipline of molecular biology deals with the study of the architectural shapes of macromolecules of biology and how they obtain such shapes such as nucleic acids and proteins. Structural biology has received enormous importance as most of the cellular activities are dependent upon these macromolecules and also because they have to coil in a particular three-dimensional figure to perform these activities. These tertiary structures of macromolecules evolve in a complicated manner on their basic primary structures. Biomolecules are naturally highly minute and can only be observed under extremely advanced light microscopes. The structures of these biomolecules are usually determined by means of measurements applied upon huge numbers of similar molecules simultaneously. Similar methods include electron cryomicroscopy (cryo-EM), ultra fast laser spectroscopy, Dual Polarisation Interferometry, NMR, circular dichroism and crystallography. Most often these methods are utilized by researches for studying still states of macromolecules. There are many variations of these methods which are employed to observe denatured molecules reassume their still states.

Structural biology term papers are mainly written in CBS/CSE writing style and at times Vancouver referencing style is also used depending upon the word limits of the paper and other such related institutional requirements. Many structural biology research papers tend to focus upon bioinformatics which that observes certain patterns among the varied sequences that cause particular shapes. Recently, it has become possible to structure accurate physical molecular models that aid in determining biological structures in the in silico study.
