Structural Biology
Structural Biology
Structural Biology (pronunciation: /ˈstrʌktʃərəl baɪˈɒlədʒi/) is a branch of biology that involves the study of the molecular structure and dynamics of biological macromolecules, particularly proteins and nucleic acids, and how alterations in their structures affect their function.
Etymology
The term "Structural Biology" is derived from the English words "structure" and "biology". "Structure" (from Latin structura) refers to the arrangement and interrelation of parts in a complex entity, and "biology" (from Greek bios, life, and -logia, study of) is the scientific study of life and living organisms.
