Conformation in biology refers to the three-dimensional shape or structure of a macromolecule, such as proteins, nucleic acids, and polysaccharides. The specific arrangement of atoms within these molecules is crucial because it determines their function and how they interact with other biological entities.
For example, a protein’s conformation will affect its ability to bind to other molecules, catalyze reactions, and perform its roles within a cell. Changes in conformation can lead to functional alterations; for instance, denaturation can occur when proteins lose their native structure due to environmental changes like pH or temperature, leading to a loss in biological activity.
Understanding conformation is integral for fields like structural biology and biochemistry, as it can help in identifying how drugs interact with target proteins and in designing therapeutics that can modulate these interactions.
