Книга: Structural Biology: Molecular Biology, Biochemistry, Biophysics, Macromolecule, Protein, Nucleic Acid, Tertiary Structure

High Quality Content by WIKIPEDIA articles! Structural biology is a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules, especially proteins and nucleic acids, how they acquire the structures they have, and how alterations in their structures affect their function. This subject is of great interest to biologists because macromolecules carry out most of the functions of cells, and because it is only by coiling into specific three-dimensional shapes that they are able to perform these functions. This architecture, the 'tertiary structure' of molecules, depends in a complicated way on the molecules' basic composition, or 'primary structures.' Structural biology is that branch of life science,which deals with the study of molecular strucuture of biological macromolecules like proteins and nucleic acids.
